Hi everyone,

Today, we are releasing an updated version of our JS SDK and DLS to address some security and TLS issues. These updates are now live on dymo.com and labelwriter.com. You will find download links below. Please note that the latest version of DLS requires the latest version of JS SDK. If you plan to update your users’ DLS version then you will also need to update the JS SDK version used in your application.

DYMO Label Framework JS SDK – http://labelwriter.com/software/dls/sdk/js/DYMO.Label.Framework.3.0.js

DLS Windows 8.7.2 – http://download.dymo.com/dymo/Software/Win/DLS8Setup.8.7.2.exe

DLS Mac 8.7.2 – http://download.dymo.com/dymo/Software/Mac/DLS8Setup.8.7.2.dmg

  1. Still no fix for multiple users being logged in to the same computer? I was excited to install and test, but no luck. When I have multiple users logged in to the same computer, printing label success is sporadic. So I tested it straight from your page at:

    http://www.labelwriter.com/software/dls/sdk/samples/js/PrintLabel/PrintLabel.html

    I hit Ctrl+F5 to make sure latest was loaded, I’ve installed 8.7.2.

    If I have multiple users logged in with Dymo web service running, I sporadically get the following message:

    http://www.labelwriter.com says
    No DYMO printers are installed. Install DYMO printers.

    If I only have one user logged in with Dymo web service running, it works every time.

    Please advise… We really need this to start working when multiple users log in to same machine.

    • Hi Owen,

      Sorry you are still having trouble… 8.7.2 should fix the problem for you.

      I can think of two possible problems:
      1. You may need to run the uninstall for each user.
      2. You may need to do a reboot after completing the 8.7.2 install.

      Check your process list in the Task Manager to make sure you have only one copy of the service running.

      Let me know if this gets you going!

      Ron

      • SOLVED: FYI: In the past, I didn’t want the web service running for users other than me, because of the problems it caused. So long ago I had disabled the service using MSConfig, and had added a shortcut to launch it in only my user’s startup folder. So when I just now upgraded, the install put the startup back in msconfig, AND my startup folder link was still there. I deleted that startup shortcut (from C:\Users\MYUSERNAME\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup).

        All is well now.

        • UPDATE: Still having issues afterall. With multiple users logged in, it fails to print labels a lot of the time. The solution is to kill the web service for that user and start it again. Then it works until a different user logs on and prints a label.

  2. Could you provide a link for the 3.0 documentation? The link should really be on every developers page in my opinion.

    • Hi Frank,

      The documentation has not been updated yet.

      Most of the changes are internal and will not effect your interface to it.
      Here is the one change:
      dymo.label.framework.init() function takes a callback as a parameter which is later invoked once initialization is finished.
      However in order to get the current status of the framework, additional call to checkEnvironment() is typically made.
      In order to make init() more user-friendly, a callback is now invoked with a parameter containing same result object that would be obtained through a call to checkEnvironment() otherwise.
      For existing code, nothing has changed since the parameter-less callback functions will continue to work with new framework.

  3. Hi,

    I just upgraded to DLS 8.7.2 on MacOS. Now, when I click the Dymo Label Web Service icon and then click “Diagnose”, I receive the message “Error: SecureChannelFailure (One or more errors occurred.)”.

    I’ve tried uninstalling and re-installing twice and I still get the same error.

    In case it helps, here is the log file from ~/.local/share/DYMO/DLS8/DLSWebServicelog – https://cl.ly/0m1j2p1r3E3k

    I see a number of errors that say “Host setup failed: None of the ports were configured to use SSL certificate”.

    Do you have any idea what is going on?

    • Hello Marc,

      I have forwarded this issue to our MacOS team. I will let you know what I here back.

      regards,
      Ron

      • I am running into the same issue, mac OS 10.12 and 10.13

        • Same. Bump. Same issue on a Mac version 8.7.2.

          • My Mac guy said this:

            This looks like certificates/keys misconfiguration, can you get list of files from ~/.config/.mono/httplistener folder by using this command in Terminal:
            > ls -al ~/.config/.mono/httplistener

            Ron

          • Marc, Mark, and Ron. I was able to fix this issue on Mac by going into my Keychain and deleting the Certificates for Dymo, Restarting my computer and then reinstalling the DLS 8.7.2 DMG, then allowed me to verify by using the diagnose option that the service was running.

          • Hi David – thanks for your suggestion, that worked for me (removing dymo certificates and then re-installing).

            @Ron – David’s solution worked for me, but just FYI – before I tried that, I ran the “ls -al ~/.config/.mono/httplistener” command and there were no files in that directory. After David’s solution, there are about 20 files that are all numerically named and ending in either .cer or .pvk.

  4. Hi,

    I get the following error message when using the new javascript framework. Any advise?

    “No access-control-allow-origin” header is present on the requested resource.

    I tried to copy paste the complete code, but your forum is blocking it because it thinks it’s spam.

    I hope you help me with this.

    Best regards,
    Bart

  5. I have the same problem, updating to the new version.

  6. Hi,

    We have been using the DYMO SDK in a x86 WPF Application for some years without troubles, but after update the DSL to version 8.7.1 we cannot print labels any more. When we try to request the label writers from Framework, SDK returns the following message:
    “Retrieving the COM class factory for component with CLSID {E8D851FA-9967-4ADF-9644-0183B9B1EA68} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).”

    Please, help! What should I do to solve this issue?

    Thank you in advance,
    Shora

    • Hi Shora,

      It sounds like some aspect of your DLS upgrade failed. Do the following:
      1 Uninstall DLS
      2 Reboot
      3 Install DLS

      I think this will fix your issue.

      regards,
      Ron

  7. Can you please add a WSDL to the printer service? This would make it much easier for languages such as Java and C# and would also help self-document the service.

  8. Is this the big update we have been waiting for that will help the Chrome browser not lose it’s connection to the DYMO? Thanks in advance.

  9. We are having CORS issues in Chrome. Your web service should supply a Allowed-Origins: * header for this to be fixed. PLEASE FIX THIS

    • Hi Bart,

      Can you give me some details about your environment?
      What version of DLS do you have installed?

      Ron

  10. It appears there is also an issue with labels created in 8.7.2 being incompatible with people running older versions of the software. after looking at the XML it appears that a MediaType=”Default” has been added to the .label XML which causes the error. Our goal is to get all of our partners that use our web app in conjunction with the dymo web service upgraded to 8.7.2 but with the “trustfailure” issue on Mac OS updating is not a reliable option.

  11. Hello,
    with the most recent Windows 10 Update, in my webapp that uses Dymo Label Writer I get the “SEC7120 error: origin not found in access-control-allow-origin header” and the Dymo stops working correctly as before.
    How can i solve it?
    Thanks in advance.

    • Hi Cris,

      Is this issue with some custom code that you wrote, or is it from our DLS software? What version of DLS?

      Ron

      • Hello,
        i use 8.7.2 with my custom web application that invokes Dymo Label Web Service; it was running fine before latest Windows update; the windows version is: Windows10, Version 1803 (build SO 17134.81) and it occurs for every browser: Edge, Chrome Firefox..

  12. When using anything other than chrome i get the following, this is from firefox dev browser:

    Request Blocked: The Same Origin Policy disallows reading the remote resource at
    *127.0.0.1 url comment spam won’t allow*/DYMO/DLS/Printing/StatusConnected. (Reason: CORS request did not succeed).

    this is viewing http://www.labelwriter.com/software/dls/sdk/samples/js/PrintLabel/PrintLabel.html too

    • Hi Daniel,

      Sorry to hear you are having these issues. I have some questions for you:
      1. What version of DLS are you running on the client machine?
      2. What version of Windows are you running?
      3. What version of Firefox had this issue?

      Ron

      • Hi Ron,

        I’m getting same error as above.
        I’m using DLS 8.7.3 version and Windows 10 enterprise. Firefox version 61

        Thanks

    • Hi Daniel,

      Can you give me some details about the client and server machines? Windows machines? Which OS?

      Ron

  13. I get the following error message on some websites. I guess it’s hosting related, but I can’t figure why it’s happening.

    Dutch:
    Kan geen verbinding maken omdat de doelcomputer de verbinding actief heeft geweigerd 127.0.0.1:80

    Translated from dutch to English (I don’t know the exact English error message)
    Can not connect because the target computer has actively rejected the connection 127.0.0.1:80

    It happens when opening label file ont he following request:
    https://127.0.0.1:41951/DYMO/DLS/Printing/OpenLabelFile?fileName=https%3A%2F%2Fsuper-shoes.nl%2Fwp-content%2Fuploads%2Fwc-dymo-labels%2FShipping%20NEW-7608.label

    It is working with other sites on different hosting.

    Any ideas?

    • Hi Bart,

      This sounds like a security issue perhaps regarding the file system. You may need to look at your browsers security settings.

      Ron

  14. We just discovered this issue when one of our employees installed DYMO DLS fresh and then received an error when trying to print custom labels from our webapp in a browser via the DYMO web service.

    Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://localhost:41951/DYMO/DLS/Printing/StatusConnected. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing).

    My question is, if we update our webapp to use the new JS SDK, will that require all users to update their DLS also? Or is the JS SDK backwards compatible? I’d like to know before attempting to update our webapp.

    Thanks

    • Hi Mike,

      Updating just your server side code will fix some issues but not all. This release was targeted at security issues, we recommend that the client and server side get upgraded.

      Ron

  15. Our application uses DYMO’s .NET Framework library but it seems that the .NET framework library is depended on the DLS version? The document says the .NET framework library has no dependency on the DYMO executable but it doesn’t seem to be the case here. We references the DYMO.Common.dll, DYMO.DLS.Runtime.dll, DYMO.Label.Framework.dll. And if we use the 8.7.0 version then any user upgraded to 8.7.1 or 8.7.2 will not be able to get a list of printers and so on. If we use 8.7.2 version then the user on 8.7.0 won’t work. This is a nightmare now in terms of deployment as now we will have to force all or our user to upgrade their DYMO software just because there’s a new DLS version.

    • Hello Lei,

      You should be referencing just DYMO.Label.Framework. Is there a reason you are referencing the other dlls?

      Ron

      • We are referencing DYMO.DLS.Runtime.dll and DYMO.Common.dll because if we make a call to DYMO.Label.Framework.Framework.GetLabelWriterPrinters() it will fail without referencing to those two other DLLs. The assembly that gets installed by DYMO DLS doesn’t seem to be in GAC. It always have the latest file in installation directory such as C:\Program Files (x86)\DYMO\DYMO Label Software\Framework but not in GAC. So our software won’t be able to get either of those two assemblies. But if we distribute those two assemblies with our software, then it seems to be version dependent. Can you provide guidance as to how we should resolve this problem?

        • Hi Lei,

          The best thing to do is compare your project with how we do it in the samples we provide. There is a C# sample that uses the framework that would be very useful for you.

          ron

          • I did reference your C# example and it references DYMO.Label.Framework.dll but on build it copies the same 3 assembly to local folder of the sample application. The sample also does not work when it is build with 8.7.0 installed and then later upgrade DLS to 8.7.2. And upon further inspection, your sample application also does not return any printer list after upgrade exactly like our application. Which boil down to where I started. I can get this working, but the SDK assembly is not installed in GAC so we have to copy to application’s folder but then newer software does not work with older assembly version. Can you suggest anything else other than the fact that we have to force all of our users onto the same DLS version?

          • Hello Lei,

            I will investigate.

            Ron

  16. Hello,

    I’ve a problem with the web service. The framework doesn’t find my printer.
    I’m running windows 10 (v. 1803) and Dymo Label Software 8.7.2 and the latest js (3.0)

    When i click on the diagnose web service button i’ve a window telling that : “The request was aborted: Could not create SSL/TLS secure channel”

    I’ve also tried to clear all cache and history etc from Edge.

    The problem is the same in Internet Explorer.

    Can anyone help me ?

    Thanks in advance,

    • Hi there,

      Is this a new problem due to an upgrade? What model number printer do you have? Can the printer be found using DLS on this computer?

      regards,
      Ron

  17. Hi,

    The version install was the 8.5.1. I’ve tried the latest version to solve the problem without success.
    The DLS find the printer.
    The printer is the LabelWriter 400 Turbo

    Thanks in advance,

    Regards,

  18. We are trying to install this on one of our Windows 7 Computers, it has installed fine on a few others but we cannot get it to install on this one. Windows 7 Professional SP1. When installing we are receiving a Windows Installer Popup with instructions on how to format the command line to install the MSI. I can manually go into our temp folder to find the MSI File and can manually install it but because it is not completing the installation the certificates don’t get installed and it won’t run. Please let us know if you need any more information, thank you.

    We found the following, just linking it because seems to be similar issue:

  19. Hi,
    Do you have .NET Standard version of protocol for label writer?
    Just producing byte stream would be great as I am writing xamarin app and can connect to BT printer directly.

    Thanks

  20. Hi,
    I have asp.net site that generates labels with 2 object fields and a barcode. It works fine on windows and the preview and the print works as expected. However when I run the site from a Mac all that shows is the barcode.

    The Label is generated via javascript using a label template and which it then sets the object fields by label.setObjectText(“”,””) and we just use label.render() to show the view.

    Not sure why the same code is returning two different results on different machines.

    • Hi Vincent,

      Are you able to debug the javascript to see that your code is running as expected on both platforms?

      Ron

      • Checking the javascript both plathforms show the same results. I do see the values getting loaded into the labelset.

        I think I’ve solved one of the labels. Windows seems to ignore the font color of the label template while the Mac enforces it. The label template that I was referencing set the object font color to white. Changing it to black shows it on both platforms.

        However, I still have 2 other older labels to try and work out.

  21. Hi,
    With the latest version of the software my Labelmanager PnP that i use for printing QR codes prints the label in poor quality and the result is a non-readable label. The last version that print with the best quality QR codes is the 8.5.1. I’m running on Windows 7 x64, also on windows 10 same quality problem

  22. I’m running into very weird CORS / host issues. The DYMO web service responds on htt ps://127. 0.0.1:419 51/ fine but throws a HTTP 405 on ht tps://l ocalhost:41 951/. This is an issue as the SDK uses ht tps://local host so no apps are working. I noticed the code calls StartHost(“127.0.0.1” and I tried replacing this with StartHost (“localhost and got an error about WCF namespace reservations, with a link to docs.micro soft.com/en-us/dotnet/frame work/wcf/feature-de tails/configuring-http-an d-https. I’m not familiar enough with .NET / WCF to go any further here, but I expect several of the above comments regarding CORS are running into this same issue.

    I’ve tried uninstalling / reinstalling and I’m definitely using the latest version.

    (Spaces added to URLs to try to get comment to post)

  23. There is an issue with the DLS Web Service in version 8.7.2. It changed the listening address in mono from localhost:41951 to 127.0.0.1:41951. Since the mono web service requires an exact header match all apps that used hxxps://localhost:41951/DYMO/DLS/Printing/StatusConnected no longer work in 8.7.2:

    $ curl hxxps://localhost:41951/DYMO/DLS/Printing/StatusConnected
    Bad Request (Invalid host)

    Reverting back to 8.6.2 fixed the issue for me:

    $ grep StartHost /Users/me/.local/share/DYMO/DLS8/DLSWebService.log

    DYMO.DLS.Printing.Host.exe Information: 0 : StartHost: hxxps://localhost:41951/DYMO/DLS/Printing

    PS: xx = tt to bypass the comment anti-spam filter

  24. Looks like the SDK works with both old and new versions of DLS, but DLS 8.7.2 only works with the newest SDK. 3rd party sites that are hosting their own SDK JS file need to update. Very annoying.

  25. Hi, we are using the latest DLS 8.7.2 on Mac OS. I am getting a “No Ports could be configured using SSL” error when diagnosing via the dymo web services widget on 10.13.5. On 10.13.6 I an able to diagnose and see the certificate is valid but when directed back to our label pages, there is an error that says “Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user’s experience. For more help http://xhr.spec.whatwg.org/

    I tested 8.7.2 on a 10.12.6 machine and have no issues reaching 127.0.0.1 or printing.

    • Hi Lawrence,

      I wonder if I can get some more information from you:
      1. What browser are you testing with?
      2. What output do you get from the terminal for this command: ls -alR.config ?
      3. Is DYMO Root CA (for localhost) cerificate installed and trusted in system Keychain?
      4. What is contained in your ~/.local/share/DYMO/DLS8/DLSWebService.log?

      Ron

      • Hi Ron,

        We are testing on Safari 11.1 and Firefox 61.

        Your terminal command does not return anything. IR.condig does not exist.

        There is no root certificate installed. I removed it when trying to troubleshoot.

        • Sorry I meant IR.config does not return anything.

          • I have reinstalled a ca root cert for localist but it is not telling me that SSL connection to 127.0.0.1 could not be established…

          • Hi Lawrence,

            Sorry, I wrote out the command wrong:
            ls -alR ~/.config

            The best way to re-install the root certificate is to un-install/ re-install DLS.

            Do you see the same script error when loading in Safari/Firefox?

            ron

  26. Is there any chance that you will have a more developer friendly npm package or a git release? We have had a number of mysterious breakages only to find out you “updated” something and we recieved no notification for the js in our codebase. I have alerts setup now for your rss feed, but It would be great if there were a paradigm of versioning. Thanks

    • +1 to this. We have the same issue, especially with breaking upgrades like 8.7.2 was. A large number of our customers upgraded to 8.7.2, which resulted in them being completely unable to use our label printing functionality until we figured this out.

      Dymo’s customers include some rather major institutions, and breaking their time-sensitive workflows is not ok. Especially with the only notification being on a relatively obscure non-customer-facing blog. There wasn’t even a deprecation warning, just “Surprise!”

      RSS doesn’t cut it. Please either set up an npm package, git release, or even CDN distribution, or… stop breaking compatibility.

  27. I am trying to use this framework with a Salesforce Lightning Component, however, I keep getting the following error:

    Uncaught TypeError: Cannot set property ‘Aa’ of undefined

    Is there a way to fix this?

    • Hi Aaron,

      Perhaps you could post the offending code so I can take a look.

      Ron

      • Ron,

        Thanks for your response. I was able to fix this issue within Salesforce. However, now I am trying to generate a preview using label.render(), but I only receive half the image. Is this a known issue?

        • Hi Aaron,

          I have not heard of this issue. I assume your label looks ok when you display it in DLS?

          Ron

  28. I’m using DLS 8.7.1 and JS SDK 3.0 in an ASP.MVC application, I’m experiencing an issue with one developer’s client (Windows 10 64-bit) running Firefox Quantum 61.0.1 and not detecting the installed DLS 8.7.1. Other browsers on the same machine DO detect the installed DLS properly and behave as expected. Other developer clients running Windows 10 64-bit and Firefox 61.0.1 DO properly detect the installed DLS.

    What would cause Firefox not to recognize the service is installed and running?

    • Hi Jonathan,

      Have you looked for any differences, with regards to security, in the way FireFox is set up?

      That is the only thing I can think of that would a cause an issue like this.

      Ron

  29. Can you please provide a non-minified JS library?

    It’s clear from reading the dozens of replies to each post here that your customers are finding it difficult to get basic answers on how to use your services.

    The JS code only connects to your proprietary web service; has zero benefit to anyone except the developers here who want to integrate with your products, and it’s minimal on your end to provide this.

    All the hard work you guys put into building these SDKs is completely diminished by not providing the basics that your customers need to use them.

  30. I see this same message in the Web Console in Firefox and it appears to be a warning with a yellow exclamation – “Synchronous XMLHttpRequest on the main thread is deprecated…” I confirmed it is a warning by filtering in/out warnings vs errors, etc. My printer prints the labels fine using the new SDK and DLS.

    • Hi Mike,

      What version of DLS are you using?
      What version of the Javascript SDK are you using?

      Ron

      • DLS v.8.7.2.45959 (Windows)
        Javascript SDK (downloaded above) DYMO.Label.Framework.3.0.js

        I tested in Chrome and it printed, and I receive a very similar message-
        [Deprecation] Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user’s experience. For more help, check https://xhr.spec.whatwg.org/.
        Td @ DYMO.Label.Framework.3.0.js:60

        That may be more helpful. I notice there is a “Td()” function at line 60, it’s fairly short, and there are XMLHttpRequest stuff in there.

        Thanks for checking it, Ron.

  31. Hi Ron

    We are having CORS issues in Chrome and Firefox. Printing is not possible using the SDK (DYMO-Label-Framework-3_0.js) and DLS 8.7.2.
    The console says: “Request Blocked: The Same Origin Policy disallows reading the remote resource at
    *127.0.0.1/[URL]/DYMO/DLS/Printing/StatusConnected. (Reason: CORS request did not succeed).”
    Can you help?

    • Hi Matthias,

      Sorry to hear you are having these issues…

      What OS are you running on?

      Ron

    • Can you also post the JS code that gave you this error?

      • Hi Ron
        It seems to be this line: var pngData = label.render();
        …in the updatePreview() function.

    • I don’t know if this helps, but I also received that error after I uninstalled old and installed new DYMO DLS and began using the updated JS code, without closing and opening my browser (Firefox) during that time. Once I closed and opened the browser, it printed without that error, though with a new warning I posted about above.

      • Hi HikingMike
        Thank you for your response. We tried that too, believe me, many times. Unfortunately it didn’t work out. I usually close the browsers anyway during the installation.

  32. Hi Ron
    It seems to be this line: var pngData = label.render();
    …in the updatePreview() function.

  33. Hi
    I have created some of test urls with the js dymo framework.ca you please test and let me know is same html as preview prints on label.
    I don’t have dymo printer with me.Before purchase I need to confirm that it printer same print as preview.
    here are the test urls :

    http://urtestsite.com/projects/web/Alex_Davnis/printing_labels/test_print/test4.html

    Please check and let me know if there is any issue.
    I need to print it on Printer : LabelWriter™ 450 Turbo , LabelWriter™ 450

  34. One of my clients is getting a Cors problem when attempting to print. They can resolve it every time by downloading the latest DLS and installing it. As you can imagine this is getting a bit tiresome for them to do this every morning.
    They are running Windows 7 on their PCs. I was wondering if their local Dymo server might be starting up with the wrong privileges or something, and reinstalling the software sets it back to the right privileges and enabling their Dymo to work.
    Any advice would be appreciated.
    PS We have over 50 clients using Dymo printers, and this is the only one affected, so appreciate it may be hard to put your finger on what might be happening/how to resolve the issue.

    • Hi Simon,

      As you have already guessed, I am going to need more information about the site that is failing. What browser and version number are they using? What OS are they on?

      Ron

      • Hi,

        We had a similar issue related to CORS. It was due to the fact that the Javascript library was not updated to latest (3.0). Older version was being loaded from cache.

        Good Luck!
