I hope everyone enjoyed their holidays!  We have had a number of issues reported, several of them were big enough that we decided to release an 8.5.3 patch version that fixes the issues that were found.

Issues Fixed:

  • Win: There were instances that caused Barcode corruption when the Barcode was rotated on a label
  • Mac: There were issues with with the Web Service refreshing the list of DYMO printers
  • Mac: Web Service method timeout is increased due to too many timeouts
  • JS: Fixed issues with Async calls
  • JS: Fixed Issue that isBroswerSupported return the wrong value
  • JS: Fix Issue with a Crash when running in IE8

Reference the following posts for additional set up information.  Keep in mind that the Web Service is built into this version of DYMO Label so the standalone install is no longer required.

Downloads:

Thanks for all the great feedback!  Let us know of any issues found, we’ll continue to give the best support we can.

Update: Fixed a typo that was referencing the wrong revision number for the Windows build

  1. Hello,
    I would like to use the Dymo javascript library from within a Google Apps Script sandboxed environment. See https://developers.google.com/apps-script/guides/html/restrictions#sandbox_mode for details. This requires the Dymo library to be served via HTTPS (mixed HTTP/HTTPS content not allowed in the sandbox). Any plans to provide the library via HTTPS, using a CDN or otherwise?
    Thanks.

    • Hi Erron,

      All the communication between our JavaScript library and the backend Web Service installed with DLS is done over HTTPS.

      • Hi dymodev,

        Thanks for your reply. But I was actually asking a different question. Sorry that I was not clear. Here’s my question in more detail.

        When I reference the JavaScript library, the reference might look something like this:
        src=http://www.labelwriter.com/software/dls/sdk/js/DYMO.Label.Framework.2.0.2.js

        But note that the library is referenced by HTTP. I need to reference it by HTTPS. Many JavaScript libraries are now made available by HTTPS. Can you make yours available by HTTPS?

        Why is this important? For any Google drive plugin (which is the scenario that matters to me), you must reference external libraries by HTTPS. Google’s rules are explained here:
        https://developers.google.com/apps-script/guides/html/restrictions#sandbox_mode

        The bigger picture is that I’ve written an Apps Script add-on for Google Sheets. Its intended purpose is to print a label from the currently selected row in a Google Sheet. It’s a very simple application, but it won’t run unless I can reference the library by HTTPS. Of course, I could set up my own web server with a certificate, but this would defeat the purpose of using a Google sheet as a simple and tiny-footprint label database.

        Thanks!

        • I don’t think that will happen. Scroll down to the post on Apr 16, 2015 and you will see this: “we recommend that you do not link to the JavaScript file that is hosted on our servers but download a copy and host on your own servers”

          You can serve it via HTTPS from Google Drive but that feature is going away on August 31, 2016. I would suggest putting it on S3 and serve it via HTTPS from there.

          • Hi Robert,
            Thanks for your reply. I will move forward with one of those options, but I hope you will reconsider in the future. While I agree that local code has some benefits, the value of being able to reference the library via HTTPS is important for simple tasks like making a Google Apps Script plugin. It is just so enticingly easy to make an Apps Script plugin to print a label from a Google sheet, but one does need the library to be HTTPS. There exists some subset of people who could use your wonderful library in this way but who wouldn’t necessarily want to go to the extra trouble of setting up a web server just to host one javascript library.
            I believe your library could be hosted at, say, cdnjs.
            Thanks!

          • Hi Erron,

            At this point there is no plan to host the library on a HTTPS server. We have always suggested that developers host their own version of the library to avoid any dependencies on our servers.

          • Erron, to be clear, I don’t work for DYMO. I am a developer like yourself.

          • OK. I am currently serving the library from the rawgit cdn for my own use, and if anyone else is trying to write an Apps Script plugin, I would encourage them to take this approach.

            (Sorry, Robert, for confusing your affiliation!)

  2. Hi, thanks for posting! What is the minimum operating system requirement on the Mac to run this? Can it only work with el capitan or can it run with 10.9 – Yosemite, 10.8 – Mavericks etc…?

    Thanks!

    David

    • Hi David,

      Our general rule when it comes to Official OS support is the current version plus 2 back. These are the OS version that we test on. This does not mean that older version will not work, we just don’t test on them. So the current Mac OSX versions that we support are 10.11, 10.9 and 10.8. For Windows, we support Windows 10, Windows 8 and Windows 7.

  3. Using the latest javascript SDK when I try to execute checkEnvironment() I get an error saying P.c() is not a function. I un-minified the code and sure enough, there is no P.c() function. It doesn’t happen when using the previous beta js file.

    • Are you running DLS Windows or Mac? Which DLS version have you installed? You encounter the issue with DYMO Label Framework 2.0.2, but it works with DYMO Label Framework 2.0.0, isn’t it? Which browser are you using?

      • DLS Windows. DLS Version 8.5.3. Correct, the error occurs with 2.0.2 but not the 2.0 beta js. I happened to be using the latest version of Chrome when the error occurred (Version 47.0.2526.106 m).

        • Could you please run the trace / debug and provide the output.

          • Were you are able to run a trace?

            In meantime I have done some more research. I’ve compared the obfuscated version of 2.0.0 and 2.0.2 framework files and they both have this function declared identically, and in same sequence point.

            I am not able to duplicate the issue. Are you able to duplicate the issue on another PC as well? Does error occur with Firefox as well? What Windows version are you running?

          • I’m too having the same issue “P.c” is not function .. Please give me a solution for this. Im using DLS version 8.5.3.1897 on windows 10. And JS framework is 2.0.2

          • Please make sure that you are calling the init() method described in the following post http://developers.dymo.com/2015/08/20/dymo-label-framework-javascript-library-2-0-open-beta/

            If you are already calling the init(0 method then please provide a trace/debug as described above.

  4. Hi Dymo,

    We’re using the dymo labelwriters for printing labels in our restaurant. Since a week or two we’re encountering problems with printing.

    When we click the button to print te dymo the following code is executed:

    Dynamo Label Sub Btn1_onclick()Dim DymoAddIn, DymoLabelSet DymoAddIn = CreateObject(“DYMO.DymoAddIn”)Set DymoLabel = CreateObject(“DYMO.DymoLabels”)DymoAddIn.Open “F:\Dymo Labelstenopzondag.lwl”

    DymoLabel.SetAddress 1,””+chr(10)+”Naam Maurice”+chr(10)+”Res 92″+chr(10)+”Tijd 20:00″+chr(10)+”Email *********”+chr(10)+”Opmerkingen Test”+chr(10)+”Telefoonnummer 20″+chr(10)+”Duur 3″+chr(10)+”Volw. 1″
    DymoAddIn.Print 1, TRUE
    window.close()End Sub Etiket wordt afgedrukt

    The websites gives us a pop-up and closes when printed. The strange thing is that it only prints one. Everytime i want to print a label i have to close and reopen IE11.

    Any idea?

  6. Hi,

    I am using the new updated version in Chrome with https.
    It can not find the DYMO Label Writer

    If I open the same website on https in Firefox it works without any problems.

    Latest DYMO Software is running on a complete new computer on Windows 7.

    Any ideas?

    • An update on this error.

      When I view it I get the following error:

      POST
      XHR
      https://localhost:41951/DYMO/DLS/Printing/PrintLabel [HTTP/1.1 400 Bad Request 15ms]
      Error: Failed to execute webservice command: 400: Bad Request

      On websites without https it works without any problems.

      Best regards,
      Bart

    • Another update on this.
      I’ve enabled the trace / debug function.

      It generates the following code:

      onEnvironmentChecked > checkResult isBrowserSupported : undefined, isFrameworkInstalled: undefined, isWebServicePresent: undefined, errorDetails: undefined

      However it is working on another https enabled website. Same browser, same scripts.
      The following debug code is generated:

      onEnvironmentChecked > checkResult isBrowserSupported : true, isFrameworkInstalled: true, isWebServicePresent: true, errorDetails:

      Wat could be wrong? No other javascript errors or something like that.

      I am not sure if it is caused by https, because it’s working on another website with https, so it could be something else.

    • In correction on my first message: It is not working on Chrome and Firefox. Both browsers give the same errors.

      • It sounds like the webservice isn’t running. Could you please run the diagnose option that is part of the web service menu? Are you running this from the same PC, same browser and same script?

        • The web Service is running.
          It is working on multiple websites, but just on that website not.

          Any ideas?

        • I’m seeing the same issue: the webservice is running (because it’s responding with status 400).

          We found that turning the webservice off and “falling back” to the browser plugin works.

          We’ve only seen this on Windows 10

  7. Hello,

    Thanks for your work on this new software!

    We’re trying out the web service for Mac & Windows. Mac worked perfectly, but we’re having a strange problem with our windows device.

    The Windows device is a Surface Pro 3, up-to-date Windows 10. It shows our printer as “isConnected: false”, despite the fact it’s plugged in by USB.

    I’ve tried a few things:

    – Running the web service as “Administrator”, and logging in as adminstrator
    – Visiting the web service endpoint directly (I can see IsConnected=False in the XML response)
    – Restarting the web service
    – Printing from the Dymo desktop software (v8.5.3.1897) — printing from that program works well.

    Do you know why it’s showing isConnected=False? Is there anything else I can do to troubleshoot?

    Thanks!

    Robert Mosolgo

    • I assume that you are running the latest DYMO Label Framework 2.0.2, isn’t it? Have you tried to run on a different Windows PC? Have you added the Init() method as it is described here http://developers.dymo.com/2015/08/20/dymo-label-framework-javascript-library-2-0-open-beta/ ? Could you enable tracing and provide the output.

      • Thanks for your response! Yes, we’re using 2.0.2. No, we don’t have another Windows computer!

        Thanks for your suggestion. When I went back to try this again, it worked!

        I’m not sure what changed. The computer was asleep all night. But today, we visited the `GetPrinters` endpoint and it showed as IsConnected=True!

        Thanks again for your help, we’ll keep testing it and let you know if we have any more trouble.

        Robert

  8. One more question, is this release still considered “beta”? Do you have any updated timeline for a production release?

    Thanks again!

    Robert

    • No, the Software listed above under downloads isn’t beta. We have release the software on the developers site so that all of our SDK developers would have the released version as fast as possible. There is overhead and process that needs to be followed in order to post the build to the website.

  9. Hi, we have started using the new javascript framework but on the Mac we are seeing that getPrinters() is inconsistently not returning the printers list. Most of our users are still on the 8-5-2 DLS and some of those using a Mac are seeing this occur.
    Our testers are reporting issues with 8-5-3 and the Mac as well and have confirmed with me that they are using the patched version of the DLS.

    Because this is inconsistent and nothing specific triggers it I just wanted to report the issue and see if others were experiencing this as well or if there is a fix in the works.

    Thanks.

  10. Thanks for the API! I just started building a webapp to manage my inventory of electronic components. I really love that you’re offering the JavaScript library (and corresponding webservice, DYMO.DLS.Printing.Host). Here’s my feedback from most-to-least desired:

    1. Put the JavaScript in a repo so I can help with these other issues.
    2. Bind the service to 0.0.0.0 instead of 127.0.0.1 and respond to requests that don’t use “localhost” in the Host header. Let the user tell the dymo.label.framework which address it should communicate with (hostname or IP).
    3. Add some error handling for invalid data and have the service manager (launchd) relaunch the service if it crashes (with limited number of retries).
    4. Add support for AMD, CommonJS, RequireJS, etc.
    5. It would be nice to have some CLI options for DYMO.DLS.Printing.Host – like –help and –port.

    Keep up the good work!

    • Hi John,

      Thank you for your feedback, I will forward these requests to our developers. I can comment on a couple of your suggestions.

      1. Unfortunately, there is no plan to make this an open source project. If this ever changes, it will be posted on this blog.
      2. We do plan on expanding this functionality in the future but for the first version, we want to limit all calls to localhost. This matches the original functionality.
      3. We would also like to add more error handling to the application. Our first focus was to make it run as close to the older version before adding newer functionality.
      4,5: We can take this under consideration when working on the next version.

      Thank you again for your feedback!

    • I am with you. Because of the hostname check we must use Charles proxy. :-(

  11. When disconnecting a printer and calling getPrinters() afterwards it is still reported as “isConnected: TRUE” on OS X in Safari and Crome! :-(

    On Windows FF/Chrome/IE the isConnected status is reported correctly. Tested on several machines.

    Can anybody confirm this problem? Any solution available? Trace reports:


    checkEnvironment > cachedWebPort : 41951
    VM110:106 checkEnvironment > trying async service discovery
    VM110:106 _createFramework > return _framework : undefined (async)

    • Are you using the latest DLS software and Javascript library? Can you give more information about OS version, printer model and any other pertinent information that can be forwarded to the developers?

  12. I’d like to know if the DYMO.Label.Framework_2.0Beta.js is still good or there is a new version.
    I’m asking that because of my customer noticed me that using Chrome the DYMO printer does not work…

    Any help is appreciated.

    Marco

    • Hi Marco,

      You should be using the latest official release of the JS library. It is linked in the following article.

      • Hi,
        Thank for the reply.

        Sorry, but I don’t understand if I need to use Web Service Beta 1 or Beta 2 Or if it’s enogh to download and install the “Windows DLS 8.5.3.1897” and use the DYMO Label Framework 2.0.2 ?

        My goal is to allow my customer to print via Chrome browser.
        Could you please help me?

        Marco

    The important message is “‘Paper ‘11352 is not supported at ‘\\BUTIK4\DYMO LabelWriter Twin Turbo'”

    • Hi Leif, A bad paper name in the label file will produce this error and will prevent printing. Could you create a new test label in DLS and use that label file to print to the LabelWriter to see if that will work?

  14. New Win10 PC – initially installed the latest software from the web site which was 8.5.1 – moved my LW450Turbo and installed – received error message – tried various compatibility settings incldg Win8 and Win7. Printer previously worked fine from either Win7Pro and Vista. Error msg was:
    “Cannot create instance of ‘MainWindow’ defined in assembly ‘DYMO.DLS, Version=8.5.1.1816, Culture=neutral, PublicKeyToken=5426002a38745af9’. Error in markup file ‘DYMO.DLS; component/MainWindow.xaml’
    ===
    Accidentally discovered this area which had v8.5.3 and indicated that it was Win10 compatible. I uninstalled v8.5.1, unplugged my LW450 and installed v8.5.3, plugged in printer. no dice – effectively same error:
    “Cannot create instance of ‘MainWindow’ defined in assembly ‘DYMO.DLS, Version=8.5.3.1889, Culture=neutral, PublicKeyToken=5426002a38745af9’. Error in markup file ‘DYMO.DLS; component/MainWindow.xaml’

    So any suggestions? Thanks Ken Schindler

  15. I’m trying to get the demo (http://www.labelwriter.com/software/dls/sdk/samples/js/PrintLabel/PrintLabel.html) working on my machine but I keep getting an error that No printer is installed. I can print using the Dymo Label Software. I’ve tried on Firefox, Chrome, and IE but I get the same results on each browser.

    I also tried using the 2.02 instead of the referenced version in demo (it may be the same one, it was titled latest version).

    In the console, dymo.label.framework.getPrinters() returns an empty array.

    When visiting the check environment page on firefox I get this result
    isBrowserSupported: true
    isFrameworkInstalled: true
    errorDetails:

    On chrome I get this result
    isBrowserSupported: true
    isFrameworkInstalled: false
    errorDetails: DYMO Label Framework Plugin is not installed

    Any suggestions?

    • Hi Matt, unfortunately, we have not had the chance to update the samples with the new Web service functionality. You will need to use DLS 8.5.3, DYMO Framework version 2.0.2 and your Javascript needs to call the init method, which is described in the this article. You can also diagnose if the web service is running correctly by calling diagnose on the DYMO Web Service located in the service tray.

      • Hi, I was wondering how to start up the DYMO Web Service on Mac after exiting? I can’t find anything, and can only seem to start it up after re-installing.

        • The following command will stop and start the Web Service:

          launchctl stop com.dymo.dls.webservice
          launchctl start com.dymo.dls.webservice

  16. We are trying to integrate the latest available Dymo Label Framework SDK into our WPF Prism MVVM application. We are running .net Framework version 4.5.2. We had an odd ReleaseHandleFailed error occur upon and during print. To troubleshoot, we created a new test project in Visual Studio 2013 w. same .net Framework version and WPF. Same error.

    We then made a sample project with same IDE and .net version. The only change to the project is it is WinForms instead of WPF. Same code, no error. Print is successful for us in WinForms only. WPF consistently throws a version of the following error:

    Managed Debugging Assistant ‘ReleaseHandleFailed’ has detected a problem in ‘C:\ … .. … .. .. \myapp.vshost.exe’.

    Additional information: A SafeHandle or CriticalHandle of type ‘MS.Internal.Printing.Configuration.SafePTProviderHandle’ failed to properly release the handle with value 0x0071BE58. This usually indicates that the handle was released incorrectly via another means (such as extracting the handle using DangerousGetHandle and closing it directly or building another SafeHandle around it.)

    I have had no luck reaching anyone regarding support of the SDK and have found no similar issues reported online. Please help me get the SDK to work properly. I can provide test projects if need be. Syntax is vb.net.

    Code is as follows:


    Private Sub Button_Click(sender As Object, e As RoutedEventArgs) Handles Button.Click
    Try
    Dim Printer As IPrinter = Nothing
    Dim Label As ILabel = Nothing
    'get collection of possible printers
    Dim Printers As IPrinters = DYMO.Label.Framework.Framework.GetPrinters()
    'check to see if we got a printer. if not, do not print
    If Printers.Count > 0 Then
    'we'll only ever have one attached, so lets just grab the first
    If Not Printers Is Nothing Then Printer = Printers.First()
    'get the label template path and load
    Dim LabelFilePath As String = "Content\Labels\pvl.label"
    Label = DYMO.Label.Framework.Framework.Open(LabelFilePath)
    'set values for label orderno1 and 2
    Label.SetObjectText("ORDERNO1", "123123123")
    Label.SetObjectText("ORDERNO2", "12321321321")
    'we need to alternate between sampleno1 and sampleno2 depending on whether we are dealing with an odd or even sample count
    Dim OddEvenCounter As Integer = 0

    Dim lsBuilder As New LabelSetBuilder
    Dim record As ILabelRecordBuilder = Nothing

    For X As Integer = 0 To 5

    OddEvenCounter += 1
    Dim IsEvenNumber As Boolean = sIsEvenNumber(OddEvenCounter)
    Dim LabelName As String

    If IsEvenNumber = False Then
    LabelName = "SAMPLENO1"
    record = lsBuilder.AddRecord()
    Else
    LabelName = "SAMPLENO2"
    End If

    record.AddText(LabelName, "123123213")

    'Label.SetObjectText(LabelName, s.SampleNo)

    'If IsEvenNumber = True Then

    Next

    Dim params As New LabelWriterPrintParams

    Label.Print(Printer, params, lsBuilder.Xml)
    End If

    Catch ex As Exception
    'HandleError(ex, "Creating Sample Labels", Nothing, True)
    End Try

    End Sub

    Public Function sIsEvenNumber(number As Integer) As Boolean
    Dim val As Integer = number Mod 2

    If val = 0 Then
    Return True
    Else
    Return False
    End If
    End Function

  17. I have a user on Windows 7 and Chrome using 8.5.3.1897 and the web service isn’t working. When I click Diagnose I get the error “none of the ports were configured to use SSL certificate”. A reboot/reinstall didn’t change anything. I had them switch to Firefox and use the plugin for now. Is there anything I can do to get it working?

    • Can you provide a log file for the web service? It is located at %LocalAppData%\DYMO\DLS8\DLSWebService.log
      Web service setup during installation is merely a launch with admin privileges and “/i” parameter, so if there were any exceptions they should have been logged.
      Also, the you may try running web service with admin privileges and without them to see if there’s any difference (system tray icon’s tooltip denotes the mode in effect: User/Admin).

  18. Where are logfiles?

    Request Error

    The server encountered an error processing the request. See server logs for more details.

    • We’re using label 11355, a label sold as 19x51mm, but actually as an extra part of 7mm on top, which we want to use.

      I can make it fit using Dymo 11352 Return Address Labels 25x54mm, but I have to start 120 twips in from the left (landscape), otherwise the letters are cut off. I’d like to use these 2mm too.

      I believe I should use CustomPaper instead of PaperName in the LWL XML
      I tried this (with the right angular brackets, but which this editor won’t allow)

      [CustomPaper]
      [Size Width=”1440″ Height=”2880″ /]
      [PrintableSize Width=”1340″ Height=”2780″ /]
      [PrintableOrigin X=”100″ Y=”100″ /]
      [/CustomPaper]

      But I just got “The server encountered an error processing the request. See server logs for more details.” when trying to print,

      If I have PaperName and CustomPaper, the CustomPaper is ignored.

      • Hi Leif, we do not officially support this manipulation of the custom paper so it is an area that you can change at your own risk. i will say that the margins around a label are there for a couple of reasons.
        1. We use it to protect label integrity.
        2. Also, depending on the size of the label, there could be print head reasons.

        • As I said, The 11355, a label sold as 19x51mm, but actually as an extra part of 7mm on top, which we want to use.

          So there actually is label at the whole area, even if the label consists of two parts.

    • The Web Service log file is located at %LocalAppData%\DYMO\DLS8\DLSWebService.log. If you can get us that file for the problem that you are running into with network printers, it could help us diagnose the issue.

  19. Hi ALl,
    I don’t understand if I need to use Web Service Beta 1 or Beta 2 Or if it’s enogh to download and install the “Windows DLS 8.5.3.1897″ and use the DYMO Label Framework 2.0.2 ?

    My goal is to allow my customer to print via Chrome browser using your JS library.

    Could you please anyone help me?

    Thanks in advance

    Marco

  20. Where would one go to report a minor bug in this release

  21. Great job guys! Works really well!

    I’m seeing some Cross-Origin errors on Windows browsers (Mac seems ok) but it doesn’t seem to be causing any issues with printing. Fingers crossed these won’t just stop it from working one day if Microsoft decide to disable the cross-origin connection.

    Will it just reverted back to the compatibility mode if for some reason it cannot connect to the port?

    • Hi Ben, Thanks for the Kudos!

      The Framework is designed to go into backward compatibility mode if it cannot connect to the port. Unfortunately, this will causes some browsers(Chrome and Edge) not to work since they do not support NPAPI.

  22. I found an error in 2.0.2, but I think it exists in previous versions as well:

    // using a xml template with one image and one text field...
    var label = dymo.label.framework.openLabelXml(labelXml);
    var labelSet = new dymo.label.framework.LabelSetBuilder();

    // #1 label
    var record = labelSet.addRecord();
    record.setBase64Image("GRAPHIC", "iVBORw0KGgoAAAANSUhEUgAAAMgAAADIAQMAAACXljzdAAAABlBMVEUAAAD///+l2Z/dAAAAvElEQVRYhd2UUQ5DIQgEuf+lt+ljF7E9wTw0Rhl/JoJVHXqG5xU0om90vrx7Mlhiz1zxHTo5tu8h/Xh04kqsJvVfoyzSoTXugBE5SmefHmOSqvE71ZgVR6KXnsoVLEnGX58yqaSL8Ve/z0TSwKrTYlwyurYcZSwZ33alk87bUrtGmWQKzz9gHJlESkb59OKKJHVVnfx6k+eR6SilMtdCJNNIRzx9RiZLWK8gu7cEJkqievWRSvJTzJtFFEk+cE+O8NJzEdsAAAAASUVORK5CYII=");
    record.setText("Name1", "Hello 1");

    // #2
    var record = labelSet.addRecord();
    record.setText("Name1", "Hello 2");

    // print it...

    Expectation:

    Two labels, the first one with an image and text “Hello 1”, the second one only with the text “Hello 2”.

    What actually happens:

    The first AND the second label do contain the image. :-( The image is not reseted when calling labelSet.addRecord() for the second label!

    Workaround for #2 label:


    // #2 label
    var record = labelSet.addRecord();
    record.setBase64Image("GRAPHIC", ""); // !!!!unset the image manually here!!!! :-( :-(
    record.setText("Name1", "Hello 2");

  23. Works perfect for me, just a little question since my taskbar on Mac is pretty cluttered. Please make a function so I can remove it off my taskbar :D

  24. Hello,
    I have a bug with DYMO Label Framework and WindowsForms apps in C#. Sample code from SDK (c#) prints label barcode (any type) correct only if a set target to .net 3.5. If I create sample app in .net 4.0 or above – 4.6 printer print only text. Barcode is empty. It not exist on paper. From DYMO Label software all is correct. I use Windows 10 x64 and Visual Studio 2015 Express for Desktop. I found if i set aligment of barcode to left the code has been printed but it is cut. The issue is on DLS 8.5.3 and previous Here is my simple code:


    using System.Windows.Forms;
    using DYMO.Label.Framework;

    namespace DymoTest
    {
    public partial class Form1 : Form
    {
    private ILabel _label;

    public Form1()
    {
    InitializeComponent();
    }

    private void button1_Click(object sender, System.EventArgs e)
    {
    _label = Framework.Open(@"test.label");

    IPrinter printer = Framework.GetPrinters()["DYMO LabelWriter 450 DUO Label"];

    _label.Print(printer); // print with default params
    }
    }
    }

    • Check the post on the home page of this blog dated Sep 30, 2015 with the title “Barcode Printing Issues”. I believe it addresses this issue and has some workarounds.

  25. I’m using latest versions of Dymo and the Framework and I’m consistently having a problem of the label printer randomly stops working. One day it works, next day it doesn’t, then on some reboots it works and others doesn’t.

    In Chrome and IE I get the error “Failed to execute webservice command: 400”.

    Last time I had to uninstall and re-install Dymo software and then it worked fine but now a few days later it’s back to the same problem.

    On Dymo Label when trying to print a label says “Printing Error: PrintTicket provider failed to convert DEVMODE to PrintTicket. Win32 error: -2147467259

    • I found the reason why the web service stops working, at first looked random but after 1 year with the problem I’ve noticed a pattern thanks to one of the days all the 4 computers with Dymo stopped printing at the same time. That’s when I noticed there was a Windows Update in all of them.

      I’ve since confirmed Windows Updates are causing the Dymo printer to stop working with “Failed to execute webservice command” they won’t even work from Dymo Software itself. The only solution is to go to Manage Devices, remove it and scan for new hardware. Takes only 20 seconds to solve but it is very annoying as my clients keep having to ask me to solve this every time it stops working.

      It seems to only happen after Windows installs some Windows Updates, not all updates cause it though.

      Was a tough diagnostic, would never guess it was linked to Windows Updates. Now I leave it to Dymo to figure out why some updates are causing this problem.

      • Hi Bruno,

        I am sorry to hear you are having so much trouble with Windows Updates. I will look into this issue to see exactly what it is about the update that is causing the problem.

        Regards,
        Jeff

  26. Hi, Thanks again for your great work on this project!

    For my use, I need online/offline detection, so I am pinging the webservice every second.

    I noticed that if you stop the webservice, it still returns `isWebServicePresent: true` from the `checkEnvironment` function.

    I’m using OSX and Chrome with Dymo 8.5.3.

    Is that the correct behavior? Or is there another way to detect the webservice presence?

    Thanks!

    Robert

  27. Hi!

    Is there any way to programmatically fall back to “compatibility mode”, where the JS library uses the browser plugin instead of the webservice? We’re worried some of our users won’t be able to update in time.

    I don’t know of any API for this. Is there one?

    I thought about looking for `isFrameworkInstalled`, but I noticed that value is reported as `true` even in Chrome, which doesn’t support the browser plugin.

    Thanks!

    Robert

  28. Hi, We’re getting responses from the Webservice with status of 400. The response body says that the “PrintTicket XML is not well-formed”. When we turn off the webservice and fallback to the browser plugin, we can print labels.

    I have prepared the info from this case, do you see anything out of ordinary? This gist includes:

    – Screenshot of the Webservice response (including stack trace)
    – The “Form Data” of the request, copied from Chrome browser tools
    – Information about the environment (OS, Dymo version, Dymo JS version)

    Do you see anything wrong with the request? Thanks so much!

  29. Hi. I had Chrome (Mac and Windows) printing to Dymo printer successfully shortly after this post.

    Now I am getting customers saying that Chrome is now not finding the Dymo printer. Works on Firefox and IE. Did Chrome update things again? Is anyone else seeing issues with Dymo and Chrome?

    Dymo software version: Version 8.5.3.2000
    DYMO.Label.Framework.2.0.2
    Chrome: Version 48.0.2564.116 (64-bit)
    Mac OS X 10.11

    Thanks!

  30. Just ran a windows installer for a winform application and keep getting an error:

    Could not register type library for file DYMO.Label.Framework.tlb

    Any ideas?

    • Meant to add this is an installer I created in Visual Studio 2013 for my application. The Dymo label software and SDK were already installed on the PC where I ran my setup.

    • Did this error originate from the DLS installer? Or from the installer of an application you have written? If it’s your application, you should not be installing any DYMO binaries. Instead, make sure DLS is installed on the client machine. DLS installs all of the necessary binaries for DYMO SDK apps to run.

  31. The label printer service seems to be case sensitive. If I send downcased xml to the service it will still reply with “true” but no label is being printed. Would it be possible to accept downcased xml as well? That would make it a lot easier to generate the label’s xml with javascript.

  32. I’ve been using the javascript framework to generate label previews and print from a Chrome extension. The labels in question are “Extra small 2up” (11353) and the previews I’ve been able to produce are very small and low resolution.

    The framework appears to reference an option for “pngUseDisplayResolution”, how can I render previews at the print resolution?

    A snippet of the javascript I’m using to generate the png is:

    _label = dymo.label.framework.openLabelXml(labelXMLdata);
    applyDataToLabel(_label, _labelData);
    var pngData = _label.render();

    • Setting pngUseDisplayResolution to true will generate a PNG using the display resolution while setting it to false will generate a PNG using the printer resolution. The PNG using the display resolution will be smaller than the one using the printer resolution.

      dymo.label.framework.createLabelRenderParamsXml() creates a XML string suitable to pass to the renderLabel function as renderParamsXml paramter.

      var label = dymo.label.framework.openLabelFile(labelXmlData);
      label.setObjectText(“TEXT”, “123????????”);
      var pngData = label.render(dymo.label.framework.createLabelRenderParamsXml({ pngUseDisplayResolution: false, flowDirecghtToLeft” }));

  33. When printing through Salesforce Integration, the labelwriter doesn’t know which side of the printer to use and defaults to the previously used side. If we print file labels on the DYMO LabelWriter TwinTurbo 450, printing in Salesforce switches to printing file labels. We need to go back into the Dymo Label software, change it to an address label, then re-print in Salesforce. Is there anything we can do to fix this?

  34. Hi there,

    Sometimes we experience a deadlock from the webservice (OSX, v8.5.3 + JS v2.0.2).

    In order to detect printers being added or removed, we ping the webservice every 500ms.

    Sometimes, when we actually print labels (request sent to `/PrintLabel`), it causes the calls to `GetPrinters` to get stuck. They show as “pending”, but they never finish.

    Here’s the Chrome network log for this case:

    https://cloud.githubusercontent.com/assets/2231765/13817548/087ccb96-eb69-11e5-9c8c-5532ae13cfb1.png

    https://cloud.githubusercontent.com/assets/2231765/13817553/0dc778ee-eb69-11e5-8360-45a3d36ee564.png

    If I open the taskbar app and click “Diagnose”, I got two different errors on two different “Diagnose” actions:

    – First, “Failure to write headers” (Sorry, I didn’t take a screenshot!)
    – Second, “Request timed out” (https://cloud.githubusercontent.com/assets/2231765/13817981/9c9d4ade-eb6a-11e5-8a9e-6a4f82eb487c.png)

    If I manually stop the service, the “pending” request finally fails.

    If I manually restart the service, then subsequent requests succeed.

    Do you know why that call hangs indefinitely? Is there something I can do to work around it?

    Thanks for your help!

    • Hi Robert,

      I will forward this information to the appropriate developers for investigation. I will follow up once we have more information.

    • Hi Robert, Could we get a copy of the script to look at?

      As a note, for the mac version, calling GetPrinters() every 500ms does not do what is expected. Due to some limitations on the mac side, the printer list is not updated with the GetPrinters() call. It is updated via the init and CheckServiceStatus request (which is sent once on DYMO JS Framework init on a web page load). GetPrinters returns a cached list.

      • Sure, I’ve pasted some application code here with minimal changes. Please excuse the CoffeeScript!

        One file is the `CheckInPrinter` which is instantiated for each print job

        The other file is the `DymoPrintersStore`, which is a singleton, long-lived object in JavaScript memory. It continually polls for changes in the printer arrangement.

        https://gist.github.com/rmosolgo/fd8c0e56d24b1fcf32a2764435748d37

        Thanks for any insights you have!

  35. Need some help, very new at this. I have an application that was written for my business. It is a web based application that prints labels when work orders are created. Print label still works in IE, but no longer works in chrome. I get plugin unsupported and no dymo printer installed errors. I’ve updated application, and framework, still not working in chrome. Do I need to do something in the php or JS to change the application from using NPAPI or something? I am a bit in over my head here, any help would be great.

  36. Is label.render() / label.renderAsync() known to be broken?

    I can successfully print a label using

    var label = openLabelXml(myXmlString);
    label.print(myPrinterName);

    However, when I try to preview the label using either label.render() or label.renderAsync(), the following happens:

    * The Javascript framework thrown an exception: “Failed to execute webservice command: RenderLabel. Error: -1”
    * The webservice crashes. See below for stack trace excerpt.
    * I have to manually restart the webservice to continue printing.

    I’m using V8.5.3 on OS X 10.10.5

    • Hi Marius,

      We are not seeing any issues with the render methods. The call stack seems to indicate that the crash is happening in parsing the render params xml. Could you send a full dump of the XHR request headers from the Chrome network log? Also, could you send the contents of myXmlString.

      There could be a possible workaround using the method: renderLabel(myXmlString,””,myPrinterName). It does the same as label.render(), but you pass an empty render params xml.

      Since it will be easier to attach files could you send the request through our mailing list: sdkreply AT newellco dot com

      Thanks

  37. I am getting this error now: onEnvironmentChecked > exception e : Unable to create DYMO.Label.Framework ActiveX object. Check that DYMO.Label.Framework is installed. Exception details: Error: Automation server can’t create object. And in IE F12 it says this: XMLHttpRequest for https://localhost:41951/DYMO/DLS/Printing/StatusConnected required Cross Origin Resource Sharing (CORS).

    Can you tell me what might be wrong?

    • And this: onEnvironmentChecked > checkResult isBrowserSupported : true, isFrameworkInstalled: false, isWebServicePresent: false, errorDetails: Unable to create DYMO.Label.Framework ActiveX object. Check that DYMO.Label.Framework is installed. Exception details: Error: Automation server can’t create object

  38. I agree with one above : everything is good but could there be an option to remove the icon from my Mac Taskbar as its not a function lots of us may use daily. I can’t turn it off from my Login Items page and I have to Exit the app from the task bar everytime I restart.
    Thank you.

    • Hi Edward,

      We will look to add more confiurability to the request list for future releases. As a note, the taskbar application is required for the Web Service to work, this is why we start it on login.

      • I deleted the DYMO software but the icon on my task bar will not go away. I’ve removed every shred of the DYMO software that I can from my mac and it still auto starts every time I turn my computer on.

        How can I get rid of it?

        • I’ll try and get to the bottom of this. Can you tell me what software you’ve installed, and what steps you’ve taken to delete it?

          Thanks

  39. New install on the latest and I am doing the same construction of the label, from the same XML definition, and calling the label.print() method and receiving a 400 Bad Request error. What am I doing wrong?

  40. Hello,
    there is a bug with the smart paste/smart print.
    The bug is that it adds extra blank row on ending on all of the printed labels just the last one is ok.
    Hope you can fix that soon as everything works great on version 7 but it’s not working on win10.

    Regards,
    Alex

  41. Hi,

    I am trying to install theis version on my Mac (10.11.3) but the package wont install. just stuck at verifying the package.

    Any ideas?

    Cheers

  42. We have a SaaS application designed for Chrome. DYMO printers worked fine before the changes last September.

    Now we have not been able to get DYMO printers recognized as a printer .. we do use an https: address. with SSL encryption.

    At this point its been over six months and we still can not use DYMO printers… will you be addressing the SSL issue in a future update?

    This affects all of our customers on MAC and PC.

    If this is NOT going to be addressed, it would be helpful to know this… as this is a highly critical issue for us.

    Also is there some way to work with a live person? as in is there a help line to call and get a technician we can TALK to about this?

    Thank you

    • Hi,

      Are you able to print to the printers successfully from DLS and not through your application?

      • yes that is correct and we can in OPERA (browser)
        Not in Firefox or Chrome

        however the program is written to be used in Chrome so we are looking for a solution there.

        TIA
        BG Support

        • Since things work in Opera, my guess is a settings issue in Firefox/Chrome. Have you tried IE as well? Perhaps there are some SSL settings in Firefox/Chrome that are causing issues?

  43. Hi, a bit off topic, but where is the place we can try to focus on making Dymo drivers work with terminal servers connected Dymo printers?

    • I’m sorry, we don’t offer support for making DYMO drivers work with terminal servers.

  44. On one machine (fortunately my own) renderlabel takes 20 seconds, on the other it takes no visible time.

    Firebug in chrome shows
    POST https://localhost:41951/DYMO/DLS/Printing/RenderLabel 200 21110ms

    All machines are windows 10 with latest from windowsupdate.

    It takes around 20 seconds to load https://localhost:41951/DYMO/DLS/Printing/GetPrinters in browser, any browser.
    It even takes 64 seconds from clicking on the diagnose link on the dymo icon in taskbar to the window appears “The service is running”
    However, there is no delay on https://localhost:41951/DYMO/DLS/Printing/Check

    I’m running the latest 8.5.3.
    I’ll save this message, remove and reinstall DLS, and see if that changes anything.

    • Aha! Got it.

      I had a samba-printer at an unreachable network, in my windows “Devices and printers”
      When I removed that printer, everything runs smooth again.

      • That’s great to hear. I’m glad that things are working again for you.

        Can you help me out with a longer description of what was going wrong (is this the issue that was bothering you in comment 13 or comment 18?) and the network/windows configuration that would let us reproduce it?

      • Nice!

        I’m trying to reproduce this one. Would you mind elaborating a bit on what was going wrong, as well as what you mean by unreachable network? I’d really appreciate it.

        Thanks.

        • Simply ;-)

          I had a ipp-printer at h t t p: / / 10.0.0.4:631/printers/printer1

          If my vpn is up, and the printer is reachable from my 192.168.1.x network, the dymo webservice works fast.

          If my vpn is down, and the printer is not reachable, the webservice have a delay of x*21 seconds. (The diagnose link from the taskbar probably have 3 calls to the webservice).

          If I delete the ipp-printer, the service is fast again.

          Sorry I said samba-printer, it’s a CUPS printer.

          • My original message were pending moderation, and seems now to be gone, explained the problem in greater detail. I hope this is enough.

      • Nice!

  45. I had to add spaces in “h t t p”, otherwise your forum software accused me of spamming….

  46. Hi,

    Since my update to Chrome 50.0.2661.87 m (64-bit) when I tru to diagnose the web service on https://localhost:41951/DYMO/DLS/Printing/Check i get an error “ERR_SSL_FALLBACK_BEYOND_MINIMUM_VERSION”
    In firefox/ie everything is working.

    Strange thing: on other pc also same chrome, don’t have this problem

    Anybody any idea?

    Grtz,

  47. hi dymo developer team

    i have installed dymo label software on a citrix environment, with xenapp 6 and dymo label software 8.3.x, and it works fine, now we make a new xenapp 7 farm, also with w2k8r2 servers, but newer .net framework (4.6), and installed dymo label software 8.5.3. but i get it not to work. when user logon, printquickutility.exe will crash, and when i open dymo label software, and klick to the adress window to edit the name or so, it will fail, it comes failure: “the given key was not present in the dictionary.” have anyone a idea, how i can get dymo label software to work? in xenapp 6 it works great! but older .net framework, but i am not sure if this is the problem!

    regards
    frank

  48. Hi Devs,

    My browser console returns the following notice (not an error) during script output:

    Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user’s experience. For more help, check

    It’s is caused by the DYMO Print scripts.

    Any ideas how to solve this?

  49. A few of our Windows 10 users are reporting a certain error from Google Chrome 50.

    If they click “Diagnose” from the task bar, it opens Chrome, but the page fails to load. Instead, they get an error:

    > This site can’t provide a secure connection
    > localhost sent an invalid response
    > learn more about this response
    > ERR_SSL_FALLBACK_BEYOND_MINIMUM_VERSION

    A similar issue is discussed here: https://productforums.google.com/forum/#!topic/chrome/ERebOROL7UM;context-place=forum/chrome

    I’m on OSX and Chrome 50 works fine for me. Also, both users _just_ reported this problem, so I’m guessing it was caused by a recent auto-update to Chrome 50.

    Some of the solutions in that discussion involve changes to the server. Is there anything we can tell our customers to do to resolve this issue?

    Thanks!

    Robert

    • I have also had users report this issue today. Appreciate any insight on this issue :)

    • I also have this issue on my Windows 10 laptop and Chrome 50.

    • It does look like the solution to this problem will require changes to the server. Chrome is continuously increasing their security checking and it looks like these particular clients have servers that are out of spec for Chrome 50 clients.

      • Windows 8.1 was out-of-date for some clients, and when all windows updates was installed it solved the issue in that case for ERR_SSL_FALLBACK_BEYOND_MINIMUM_VERSION

        We have a few clients on windows 10 which is still getting ERR_SSL_FALLBACK_BEYOND_MINIMUM_VERSION, and we made sure the computers are 100% up to date with 8.5.3 and we still get error.

        Is there a windows application / package dependency for getting SSL working correctly with Chrome?
        My understanding is that the application running the secure localhost dymo webservice is trying to push too old of a certificate and chrome won’t fallback to the old certificate method.

      • Hi Robert,

        We have been attempting to recreate this issue in our lab and have not had much success. Can you give us some additional info on the machines that are having issues?

        What Version of Windows? 32 bit or 64 bit? What is the build number?
        What version of Chrome? 32 bit or 64 bit? What is the build number? What plugins are installed?

        Thanks!

        • Hi there,

          I’m not Robert, but I work with him. Here’s some info we were able to gather:

        • I’m getting the same ERR_SSL_FALLBACK_BEYOND_MINIMUM_VERSION error when i go to the https://localhost:/DYMO/DLS/Printing/Check page(only in Chrome).

          Windows 10 Pro build: 10.0.10586
          Chrome: 51.0.2704.79 m (64-bit)

          I’ve launched Chrome in incognito mode(no plugins)

          Let me know if you’ll be able to reproduce this.

  50. Same problem here since chrome 50.

    I’ve 3 computers in LAN.

    – One where my dymo is connected via USB on windows 10 and chrome 50 and it works fine
    – One with Windows 8.1 and chrome 50 where I usually use my dymo via network : If I click diagnostic the ssl certificate is fine but when I want to print I’ve a “Failed to execute web service command: 400: Bad Request” error.
    – One with Windows 10 and chrome 50 where I usualy use my dymo via network : If I click diagnostic I’ve the ERR_SSL_FALLBACK_BEYOND_MINIMUM_VERSION error mentionned above, and if I want to print I’ve the 400 bad request error.

    I couldn’t find a solution for now and that’s pretty annoying…

  51. After 2 days of testing with different services I was able to print a label trough web with https://github.com/flavienliger/DymoWebservice

    Anyway, now I’m not able to print label 11354 (error: not supported by your printer) but actually it is.
    Even trough chrome default printing service I can print in 11354 but new Dymo software don’t allow that, where is the problem now?

  52. I am trying to use LabelWrite 450 wit label Small30334. I have designed the label in DYMO Label and can print from the DYMO Label app.
    When I try to print to it from the browser, I get the “Request Error”. Printing using the XML setup of label “30252 Address” I get no error, it prints.

    Code is below.

    var tapeLabel;
    var printer;

    function printLabel(text) {
    label = tapeLabel;
    objName = “Name”; // name of the object on the label, you could have multiple
    // set data
    // Because Android does not support XPath (that is needed for setObjectText)
    // we will use LabelSet instead
    //label.setObjectText(objName, text);
    var labelSet = new dymo.label.framework.LabelSetBuilder();
    labelSet.addRecord().setText(objName, text);

    // print
    label.print(printer.name, null, labelSet.toString());
    }

  53. Any chance we’ll see the ability to use an ACL on the web service instead of being locked to “localhost”? Being able to connect a printer to a single machine and other hosts on the network being able to print to it would be helpful.

  54. It would be great to have the javascript SDK able to print a files. e.g. dymo.label.framework.openLabelFile(file_base64_encoded);

    Printing PDF labels via third party software like foxit reader remotely is a pain when it could be done locally via the SDK and webservice.

    Thanks

  55. I have 2 network dymo printers. 1 regular 450 Turbo and 1 450 DUO. he DUO is intalled as 2 seperate printers. When I start the webpage and check te printers I get 3 results (names). So far so good. The are also recognized:

    C: “”
    c: “”
    isAutoCutSupported: true
    isConnected: true
    isLocal: false
    modelName: “DYMO LabelWriter 450 DUO Tape”
    name: “\\server.domain.local\NAME1-Tape”
    printerType: “TapePrinter”

    The three printers are:

    \\server.domain.local\NAME1-Label
    \\server.domain.local\NAME1-Tape
    \\server.domain.local\NAME2

    When I try to print to them, I get the error:
    printLabe(): unknown printer \\server.domain.local\NAME1-Tape

    Anyone any ideas?

    • When connecting the printer locally it prints fine and the name is “DYMO LabelWriter 450 DUO Tape”
      What am I doing wrong when the printer is detected but the name is not recognized.

      • Please make sure that you have installed the required software on all the PC you are using. The following blog post describes which software needs to be installed on which system http://developers.dymo.com/2010/06/15/label-printing-and-web-deployment/

        If that doesn’t help, please elaborate more on your client-server setup/configuration. Furthermore are you able to print from the client as well as the server to the DYMO printer when using DYMO Label Software (DLS)?

  56. Is it possible to update the way you set/get/remove the ServicePort setting from window.localStorage? Use the setItem, getItem and removeItem.


    function Pd(a) {
    window.localStorage ? a ? window.localStorage.setItem('ServicePort', a) : window.localStorage.removeItem('ServicePort') : Ld() ? a ? Md("ServicePort", a, 100) : Md("ServicePort", "", 100) : window.c = a

  57. Hi,

    Is it possible to use the c# assembly on mac with mono c#?

  58. Hello,

    I am using DYMO.Label.Framework.2.0.2.js with the latest 8.5.3…. software on a windows 10 computer from a chrome browser with a dymo labelWriter 450.

    I stepped through my code and it creates the error:

    failed to execute webserver command 400

    when I issue the command:

    label.print(printerName);

    The same label works find on another computer

    Can you help?

    • Let’s try and narrow down what is causing the issue:

      Can you try another browser from your Windows 10 box, and then Chrome from the working machine?

      • We have tried chrome and IE with the same result. When I said “The same label works find on another computer”, I meant when I move the printer to another computer and try it, the label prints fine point being the label itself and my code seems to be fine.

        • It seems likely that this is a permissions issue of some kind, since the same message works with the same program installed in a different environment.

          First things first, can you verify that the web service is running? (Should be a DLS logo icon in the notification area, right click on it and you’ll see something like “Started on port 41951”).

          If that icon is there you should see an option to “Diagnose” in the right click context menu. If that’s there, would you click on it and let me know what it says?

          Thanks

          • When I click that it does give the positive message that the web service is running fine:

            Congratulations! DLS Web Service is up and running.
            You can now print from supported web sites.

          • Roger,

            Can you try going to http://www.labelwriter.com/software/dls/sdk/samples/js/PrintMeThatLabel/pl.html and see if you are able to print from there?

            Thanks

          • Well I tried it on my own computer where the labels print fine, and the printer list is blank, I tried resetting the printer to no avail, so I can’t even try to print as it says, “select printer”. I’ll see what my client says.

          • Same result from my client it says: “select printer” when they try to print.

          • You might have the old (javascript) sdk on these machines. Can you verify that you have the latest (8.5.3) version of DLS installed on them? Blank printer list usually means older sdk.

          • Both my computer and my clients computer has version 8.5.3.1897, mine windows vista, theirs on windows 10.

          • Any more news on this? This is really taking a long time to get and solutions…

          • Roger,

            Can you enabled the trace functionality mentioned in the following post and let us know your findings?

          • Hi Roger, sorry to hear that this is still troubling you a month on.

            There wasn’t any real gotchas in that stack trace.

            Let’s take stock, I want to make sure that we fully understand your problem.

            You have machine A, where you have your code and your printer, and attempting to print gives you a 400 error.
            You have machine B, where you run the SAME code, and use the SAME printer, and it prints fine.

            If that’s true, then the problem can’t be in your code, and there can’t be anything wrong with your printer. There must be some difference in how the two machines are configured. It is hard to diagnose that over a message board, but can you check for any obvious differences between A and B? Maybe you are logged in as an Admin on one and not the other, or a firewall is blocking the web service on A but not on B…. There must be some difference between the two.

            -Regards,
            Walter

        • Both machines are getting the code from a webserver. Both machines have their own Dymo LabelWriter 450.
          One machine is windows 10 Home (works), the other is windows 10 Pro (does not work). On both machines using the Dymo Label Service icon diagnose option indicates that the service is running and the test page that comes up says: “Congratulations! The DSL Web Services is up and running. Is it possible that on the machine that does not work that even though the diagnose option says it’s fine, that the firewall is still blocking something?

          • I don’t think that’s the case, like you said it is able to satisfy itself in the diagnose option. As far as the web service goes it believes that it is still sitting there waiting for connections.

            So, if we know that your code works, and we know that the webservice works, the question is what is different between the two computers. Obviously there’s the OS, but that shouldn’t really affect this.

            Let’s try and figure out what on that box is stopping us. Here are a few things to try on the box that isn’t working:

            1: Can you try http://www.labelwriter.com/software/dls/sdk/samples/js/PrintMeThatLabel/pl.html again? I know you tried that once before, but I fixed a bug in it yesterday. It should be working now.
            2: If you install DLS 8.5.3 on this box and run it, does that work?
            3: If you try the code samples in the SDK download, do those work?

            I’m mostly trying to see if there is anything we can do to get the printer working on this box, then if we have it working, we can try and work back to see what is different from the case where it works to what we are doing in your code.

          • Hello, so once I tried the new link you gave me that worked, the printer was listed in the drop down box. Then to my surprise my client tried my program and it worked! I was working for a while then yesterday it stopped, and your link also no longer detects the printer and nothing has been installed on the computer. I also tried a computer that was always working on a Mac and it now does not work. So frustrated. Any thoughts?

          • Also, i there a way to print directly through the desktop software vai COM or something? It does print fine to the printer..

  59. We have identified an issue with Chrome 50 not being able to contact the Web Service due to the service using an older version of SSL/TLS. This is causing the ERR_SSL_FALLBACK_BEYOND_MINIMUM_VERSION that others are seeing.

    We have several clients that are using the DYMO 450 Turbo who are unable to use the service from Chrome since the update to 50. Downgrading to a past version (We’ve been recommending 46 since that’s the latest older version that I can find a link to). Everything works fine in the most recent versions of Firefox, Edge, and Safari.

    We can reliably reproduce the issue; if you need help setting it up, please let me know.

    • Hi Chris, We’d love to take you up on that offer. Our in house guys are having trouble reproducing the issue. Can you post a step-by-step of what you had to do to get it reliably showing up?

      Thanks!

      • Recreate steps for error:

        1. In windows, Open Dymo webservice
        2. Select “Diagnose” > “DYMO Label Web service is running on port 41951. Do you want to open a test page to check the certificate” – > Select “Yes”
        3. Chrome version 52.0.2743.116 opens URI: https://localhost:41951/DYMO/DLS/Printing/Check >

        This site can’t provide a secure connection

        localhost sent an invalid response.
        ERR_SSL_FALLBACK_BEYOND_MINIMUM_VERSION

        When using MS Edge browser works:
        Congratulations! DLS Web Service is up and running.
        You can now print from supported web sites.

        The problem with the webservice running in the background is using TLS version that is using a depreciated version Chrome doesn’t like…but edge does!

      • Hey, Walter – Were you able to recreate the problem with the steps we laid out?

        Like I said, our clients can’t print their DYMO labels with the latest Chrome browser.

        We have been asking our customers to down-grade their browsers as a work around. However, most get auto-updated and don’t realize it and wonder why they can’t print.

        Please let me know.

        Thanks.

        • Chris,

          Ultimately it seems like this is going to have to get fixed in the next release for DLS. In the meantime, can you start Chrome with the –ssl-version-fallback-min=ssl3 option?

          • Walter – Thanks for getting back to us.

            We tried to run chrome with –ssl-version-fallback-min=ssl3 option with the following steps:

            1. Added ” –ssl-version-fallback-min=ssl3″ option to end of target in chrome shortcut)
            2. Right-clicked on DYMO webservice and selected “Diagnose…” > DYMO Label Web service is running on port 41951. Do you want to open a test page to check the certificate?” > Selected Yes
            3. Browser displays:

            This site can’t provide a secure connection

            localhost sent an invalid response.
            ERR_SSL_FALLBACK_BEYOND_MINIMUM_VERSION

            Did we miss any step(s)?

            Thanks again, Walter.

          • Also, Walter. Can you give me a timeframe or best guess when the next release for DLS will be?

            Thanks.

          • Work is underway on a new version, but there isn’t a timeframe yet. I’m sorry for the inconvenience that this is putting you through.

          • Hey, Walter – Any updates on a release to solve this issue?

            Thanks,

            -Matt

          • Matt, I’m sorry, we don’t have anything for you yet.

            This page -> http://developers.dymo.com/2016/08/08/dymo-label-web-service-faq/

            is still our latest word on this. I imagine that you’ve already seen that though.

          • Does DYMO have a new release for October?

            Thanks!

          • Walter – Did this issue ever get resolved?

          • Yes, I am updated to DYMO Label v.8.6.611.42161 and when I follow the steps you outline (right click on webservice icon, choose Diagnose, click yes) in Chrome I am able to see the /Printing/Check page.

      • Hey, Walter.

        A friendly ask about the status of an update to the ERR_SSL_FALLBACK_BEYOND_MINIMUM_VERSION ?

  60. Hello,

    I am having trouble printing with the async method calls. I can use the non-async calls without any issue.

    I am using DYMO.Label.Framework.2.0.2.js in my web application, I have installed 8.5.3.1897 on my computer. I am using Chrome browser. I am receiving this error: invokeWsCommandAsync > Failed to execute webservice command: PrintLabel. Error: 400
    The server encountered an error processing the request. The exception message is ‘Unable to load label template’. See server logs for more details. The exception stack trace is:

    When I access this page: http://www.labelwriter.com/software/dls/sdk/samples/js/PrintMeThatLabel/pl.html
    The printer list is blank. Not sure if the webservice isn’t working properly or not.

    • Can you enabled the trace functionality mentioned in http://developers.dymo.com/2016/08/08/dymo-label-web-service-faq/ and let us know your findings?

      • Here are the trace results.

        • Any ideas on this?

        • Typically, this exception is caused by either the label type isn’t supported on the particular printer or the label data is incorrect. Please check the response data since it should provide more details on the error.

  61. Hi, I have win7 64 bits. I’m want to install my Dymo labelwriter 400 turbo. At the end of the installation and error occurs “command.com not found”. Please help.

  62. Mac Safari 10.0 seems to have broken the DYMO plugin. Label printing was working fine on Safari 9.1.3. Then I upgraded the browser, and the plugin isn’t even being detected. I reinstalled DLS 8.5.3.2009, and I verified that Safari | Preferences | Security | Plug-in Settings is set to Ask for my web site. When I come to the page that does the printing, it used to ask me to Trust the plugin. Now it does nothing. Continuing on, that obviously means I get undefined back from the dymo.label.framework.getPrinters() call.

    Not sure if we need a new DLS install to update the plugin or a new js file to deal with new Safari 10 behavior. Any ideas?

    • Hi Dan,

      Have you tried using our web service instead? The plug-ins will eventually become unsupported as the web service method is what we’re moving to.

      Regards,
      Jeff

  63. Due to paypal’s upcoming changes to ssl requirements we disabled TLS 1.0 and 1.1 and enabled 1.2 on our windows server. This broke the javascript dsk resulting in NPO errors.

    Does anyone know if the web service will work on a windows server over https with only TLS 1.2 enabled?

  64. Anyone who can help me with teamviewer to get this working in Firefox?

  65. getting message the given key was not present in the dictionary, can not create or alter a label. Using v.8.5.1.1816
    Please help
    Thank you Eddie
