This blog post will show how easy is to add label printing capabilities to your web application. This is possible because of the JavaScript library that is a part of new DYMO Label Framework.

Prerequisites

To be able to use the library DYMO Label software should be installed on the client machines. On Windows version 8.3 or later is required.  Version 8.3.1.1332 is available on http://download.dymo.com/download/Win/DLS8Setup.8.3.1.1332.exe On Mac version 8.2.2.1173 or later is required. Version 8.2.2.1173 is available on http://www.labelwriter.com/software/dls/mac/DLS8Setup.8.2.2.1173.dmg

The Sample

The complete sample is available on http://www.labelwriter.com/software/dls/sdk/samples/js/PrintLabel/PrintLabel.html

The code in the sample is in http://www.labelwriter.com/software/dls/sdk/samples/js/PrintLabel/PrintLabel.js

The sample is minimalistic. It just contains a text area element to specify a text to be printed on a label and a button that triggers printing.

DYMOLabelFramework.js

The first thing should be done for any web project that uses the Framework is to include the library’s code, so it is available for scripts on the page. It is done like this:

<script src="http://labelwriter.com/software/dls/sdk/js/DYMO.Label.Framework.latest.js"
        type="text/javascript" charset="UTF-8"> </script>

This will include the latest version of the library. The only other hosted version for now is http://labelwriter.com/software/dls/sdk/js/DYMO.Label.Framework.1.0.beta.js

In the future other versions will be available as well. It is OK to host the file on your own web-server.

Print a Label

All printing code is in the printButton.onclick event handler assigned in PrintLabel.js. The print task contains three major steps: specifying label layout to print, setting data to print, selecting printer to print on, and actual printing.

Specify Label Layout to Print

Before a label can be printed we should specify what is the label, what objects it contains, what are their positions, etc. It is done by “opening” a label. The easiest way is to put the xml string describing the label right into openLabelXml() function. The easiest way to obtain the xml is to design the label using DYMO Label software, saving it into a file, then pasting file content into the js code.

var labelXml = '
 <DieCutLabel Version="8.0" Units="twips">
 <PaperOrientation>Landscape</PaperOrientation>
 <Id>Address</Id>
 <PaperName>30252 Address</PaperName>
 <DrawCommands/>
 <ObjectInfo>
 <TextObject>
 <Name>Text</Name>
 <ForeColor Alpha="255" Red="0" Green="0" Blue="0" />
 <BackColor Alpha="0" Red="255" Green="255" Blue="255" />
 <LinkedObjectName></LinkedObjectName>
 <Rotation>Rotation0</Rotation>
 <IsMirrored>False</IsMirrored>
 <IsVariable>True</IsVariable>
 <HorizontalAlignment>Left</HorizontalAlignment>
 <VerticalAlignment>Middle</VerticalAlignment>
 <TextFitMode>ShrinkToFit</TextFitMode>
 <UseFullFontHeight>True</UseFullFontHeight>
 <Verticalized>False</Verticalized>
 <StyledText/>
 </TextObject>
 <Bounds X="332" Y="150" Width="4455" Height="1260" />
 </ObjectInfo>
 </DieCutLabel>';
var label = dymo.label.framework.openLabelXml(labelXml);

In a real web application you would probably load the label definition xml from the server using some AJAX library instead of specifying it directly in a js file.

Setting Data to Print

The next step is to specify data to print on the label. This is easy:

label.setObjectText("Text", textTextArea.value);

The code sets the content for the object named “Text” to whatever is typed in the text area field on the page. Note: the library supports setting formatted/styled text as well. This ability will be reviewed in a different blog post.

Selecting the Printer to Print on

The printer should be selected from a list of installed printers. For this sample we choose the first LabelWriter printer:

var printers = dymo.label.framework.getPrinters();
if (printers.length == 0)
    throw "No DYMO printers are installed. Install DYMO printers.";

var printerName = "";
for (var i = 0; i < printers.length; ++i)
{
    var printer = printers[i];
    if (printer.printerType == "LabelWriterPrinter")
    {
        printerName = printer.name;
        break;
    }
}

Actual Printing

If the printer name is known the printing is simple:

label.print(printerName);

Conclusion

As you can see, label printing is not hard if DYMO Label Framework is being used. The Framework has a lot of other useful features, like multiple label printing, specifying image data for a label, specifying text styles, etc. These features will be reviewed in later posts.

  1. Great work, I like the direction this is headed! A few comments though: I think you should consider using JSON instead of XML. It is a much easier format to work with in JavaScript, lighter weight, and a format most web developers are much more familiar with. I also noticed the framework JavaScript file contains quite a bit of XML utility functions that could probably be simplified or removed all together if JSON were used. I didn’t study the code too closely, but if the XML format is needed, it would probably be easier to process the data in JSON and then later serialize it to XML rather than messing with XML the whole time.

    I look forward to seeing further development of this framework!
    Thanks
    -MH

    • Thanks for the comments and suggestions. We might add JSON support in the future. As for now, couple of words in defence of Xml :)

      • Though it is possible to specify the label in embedded xml (as some samples do) usually you would design a label layout inside DYMO Label software and store the label file on the server to load it dynamically. So, usually you don’t have to manipulate xml directly, and for specifying label data there are APIs
      • Usually label layouts are simple, but the complete schema is quite complex. Implementing it in JSON is not hard but requires some efforts
      • Most of internal xml code is to provide cross-browser interface to xml capabilities. It can be easily avoided by adding a dependence on some other js-library, e.g. jQuery. For the first release we decided not to do that.
  2. I also would like to use this framework, however, a few words on your defense of xml.

    On your first bullet. If I was inclined to store files serverside, I would not store them in XML. I don’t agree how this is a justification for XML or use of XML in javascript. Even if I was forced to save files as XML, I would much rather have a service on the server to convert to JSON than convert client side or also save a JSON copy. Another approach is if these files are small and static, you could have a package manager where the consumer of your lib can pre package them saving hits on your servers.

    On your second bullet I will refer you to http://www.json.org/fatfree.html . JSON is very robust.

    On your third bullet. This is why you use JSON, so you don’t need to depend on a js lib like jQuery for xml support. You would be able to slim down your code to make it more simple if you would not use xml. Your sorta proving Mikes point with this statement :D. My simplification of your third point is “most of the code we added is to support XML” which seems odd.

    • your points are valid. Just don’t forget, we have to support a variety of platforms and tools, and having two complex transport formats is a little overkill at present point. And for most developers XML is more familiar, even though you don’t usually work directly with it from SDK. From bandwidth point you can always use a compression. And even for JSON you do need external libraries to support older browsers.

  3. Just tried this but getting incorrect label format when pressing print even If I copy the sample app any ideas?

  4. Hi Vladimir,

    Very werid did some more comparing and it seems by adding charset=”UTF-8″ onto both the external javascript files it fixed the issue!

    The good news it’s working great on the PC now however the bad news we are deploying this label printer on a Mac OS X 10.4 computer (tester it on 10.5 though). It does seem to through up unsupported function when using Sarafi for GetPrinters() so I commented out that block of code and hardcoded it to label.print(“DYMO LabelWriter 450 Turbo”); but still get the same issue.

    How can we run this on the mac? (ideally firefox but Sarafi would be fine too), we are running the latest dmg image for mac os x listed above too.

    Thanks,
    Chris

    • What is exactly the error? Could you attach/e-mail system debug messages using Console utility? vbuzuev at dymo dot com

    • I had the same problem as chris, when i tried to print on mac os x 10.4 the print job would appear with the correct name “Dymo LabelWriter 450” but never print… chris was on the right track with hardcoding the name but i found that when you go to printer utilities and double click on the dymo labelwriter the name for mine (Dymo LabelWriter 450) was instead “LabelWriter 450” once i hardcoded this name into the script it worked fine! hope this helps someone else

  5. Can you shed some light on why Safari is the only supported browser on the Mac? I have a target application for the javascript framework on Macs, but the browsers are Chrome and Firefox…

  6. I’m using the new javascript interface, and am able to successfully print labels through Safari on MacOS 10.6 on a Labelwriter Duo. However, the print quality on the labels varies…often there are light vertical lines though the text and graphics. Sometimes the label prints much more slowly than other times.

    I am passing in the params for ‘BarcodeAndGraphics’ print quality, but it doesn’t seem to help any.

    Print quality is similar when I print through the regular Dymo label designer app.

    Suggestions?

    Thanks.

    • The print speed is different for BarcodeAndGraphics and Text (default) modes, so it is expected. As for the vertical lines – could you send the label file you are printing? and maybe a images of the printed labels? Could you print the same file from Windows? is the quality the same?

  7. Just a quick question, as I am about to test this but it may save me some time. The first paragraph says “…DYMO Label software should be installed …” Does this mean that you don’t need to have it installed? IE, if I plug in my dymo and just install the driver, will I be able to print a label to it with the javascript framework?

  8. It’s working fine on my computers (windows & mac). I have two customers testing it and both seem to be hanging at “var printers = dymo.label.framework.getPrinters();”

    btw – both could print using the non framework method with the addin activex.

    They are both on Windows XP with modern versions of IE. They are both on school district owned computers with tight security if permissions might be an issue.

    Any ideas or direction on how to diagnose this? Can I catch the error with try/catch?

  9. OK, so this isn’t ready for use on client’s machine yet. Then, I’m back to embedding the DYMOLabelPlugin in Safari on the Mac. And this brings me back to my original question, how do you open a template file from a url in Safari on Mac? Is there comparable method to ‘openUrl’ we use in windows? I can’t find it on the mac version. I need this now for a client. I guess I misunderstood and thought you were suggesting the framework as the solution I need.

    • You can install it on clients we just don’t recommend it (build 1026 is pretty stable but was not tested by QA). Just don’t forget to update to upcoming “production” version of DYMO Label 8.3 in a week or so. If you cannot wait, then possible there are two ways. First is to use your original code on Windows, and the Framework on Mac. Otherwise, call Safari plug-in directly by using openLabelFile(uri) function.

  10. How do you specify the tray number to print to using Javascript for a LabelWriter 450 Twin Turbo? I cannot find any samples that explain this syntax. Thanks!

  11. Verry nice feature! Saves me a lot of time :-)

    Very curious about how I can add an image to the labels.

    • if you image is static (not needed to be changed for every label printed), then the easiest way is to edit a label file using DYMO Label software, then you can load the label file in your java script code using openLabelFile() or openLabelXml(). If the image is dynamic then you can use dymo.label.framework.loadImageAsPngBase64() to load image from a local file or url. The returned string can be passed to label.setObjectText. loadImageAsPngBase64() has one drawback – it is called synchronously, so if it is used to load an image from an url and the site is down the application/browser will “hang” for a while. so, the better way is to load it asynchronously from the server using Ajax and then pass to setObjectText or labelSetBuilder.addRecord().setBase64Image(). Just note, that the image data should be rturned by the server as png base64-encoded string.

      Here is a sample.

  12. I’m just trying to build a web page or touch screen app that prints a saved label when an icon on the page is clicked or touched using touch screen. I don’t need to input text into the label just print it. each icon would represent a different label to print.any suggestions.

    • Just call openLabelXml() and then label.print(). One note though – currently the library is supported on Windows and Mac only.

      • can you give me an example? I dont code much (ever) say the filename is c:45×45.label what would I script and how can I tie that to a button on the web page.

        • assuming that the label file is on the web server in the same folder as the html file, the printer name is “DYMO LabelWriter 450 Turbo”, and you are using jQuery, the code would be


          printButton.onclick = function()
          {
          $.get('45x45.label', function(labelXml)
          {
          var label = dymo.label.framework.openLabelXml(labelXml);
          label.print(“DYMO LabelWriter 450 Turbo”);
          });
          }

      • makes sense and I’m sure it will work but I’m limited to Dreamweavercs3, visual studio 2008, and publisher 2007, and you guessed it not a lot of skills in any of them. but hopefully I can pass this code on to a web dev that can figure out how to make a square area on a web page print the labels. thanks, TS

  13. If you try to print a label containing the character ‘&’, an error wil apear. It seems that HTML entities aren’t converted or something. Maybe a solution would be to convert these special characters(?)

    • could you provide an example when it does not work? Are you using the latest js from the labelwriter.com?

      Thanks,
      Vladimir

      • Hi Vladimir,

        Yes, i use the latest version. The error i get:

        “Error calling method on NPObject! [plugin exception: Unable to load label template].”

        This is when i use an ‘&’ char in the label.

        Other question (maybe for other forum): I’m also intrested in the CardScan-product from Dymo, does this product also have an API so i can convert the data from a business card into my own CRM?

        • How do you put ‘&’ on the label? Could you provide a code sample? Are you loading dymo.labek.framework.js from our url? If yes, whitch one? (Just to make sure you are using the latest version)

  14. Where can i find the API for the SDK.

    • Right now, the only documentation available is the samples on the blog. Official documentation will be released in coming weeks. Current samples cover most functionality. If you have specific questions, just ask.

  15. here is my requirement.

    I am working with a java web application.
    The application background process will generate the label data along with the barcode in code128.
    The generation of the barcode should be a background process and should be hidden from the user(the ones that are connected to the printer). The value of barcode will depend on the user actions on the front end.
    I am using javascript/jquery/ajax tools.
    I want to use a standard label template for code 128 and store that template on the server. I want the dynamic label data to be populated into this template and then print action to take place on the client side.

    Please guide me. Appreciate your help.

    • You don’t need to modify the label template on the server. Just design it using DYMO Label software, assign a name for your barcode object (default is ‘BARCODE’), save it (say ‘Barcode.label’) and put on your web site. Then you can set barcode data and print a label on the user machine using following code snippet.

      var barcodeData = '0123456789'; // get from user or server
      $.get('Barcode.label', function(labelXml)
      {
          var label = dymo.label.framework.openLabelXml(labelXml);
          label.setObjectText('BARCODE', barcodeData);
      
          label.print(“DYMO LabelWriter 450 Turbo”);
      
      }, 'text');
      • Vladimir

        Thank you for your help.
        If you could provide more insight line by line of the code provided above $.get(…) would be much appreciated.

        I wonder if we can download style sheet PreviewAndPrintLabel.css for the sample example provided, that would be great too as I am trying to set up this PreviewAndPrintLabel example in my Java development environment eclipse and because css is not there, I am not getting to see the actions on the page.

        Appreciate your help.

        Thanks
        Durga

  16. I read the comments in this forum and understood what is happening inside the $.get(…). and Thanks to your descriptive clarrifications.

    I found only html and js files for the sample PreviewAndPrintLabel. Could you pls. tell me where is css provided for the download.

    One thing that I am still not clarified is when a label template is designed, created and placed on the server, why, The SDK installation is required on all the client machines that are connected to their respective printers.

  17. Could you provide the images that are referred by css. I appreciate.

  18. I copied all the button images.
    I am not able to input the text in the current address text area and also not able to see any label preview.

  19. Could you pls. tell me if I have to do any additional steps to make the sample to work as a complete application on my local machine. Appreciate your help

  20. addressDiv is not found in css. Is there any other css that this sample is refering to.

  21. I have installed the SDK 8.3 and attached 2 dymo printers to my computer.
    I am not able to see the label preview and not able to input anything in the text area provided
    any thoughts??

  22. one of the printers is dymo 450 and the other is dymo 400 both are label writers

  23. the sample you provided printLabel is working just fine on my local.
    I am working with previewandprintLabel example you provided because it is similar to what I have to do

  24. click Check button. What is the output?
    isBrowserSupported: true
    isFrameworkInstalled: true
    errorDetails:

    does http://labelwriter.com/software/dls/sdk/samples/js/PreviewAndPrintLabel/PreviewAndPrintLabel.html work?

    yes it does work
    I could print labels.

  25. Vladimir,

    I Thank you alot for the help you have provided. Now, I could print the bar code labels from the application that I have created in java environment. I tried to print bar code from a different computer on the network that do not have SDK installed by accessing the application I had created on my server. The remote computer has printer connections and drivers installed but no SDK. It did not print. I ask you again, is the SDK mandatory on all the cliets to be able to print from a web server application? Pls. confirm

    Thanks,
    Durga

  26. Hey, great post!

    Is there a way to print to a client’s DYMO printer without requiring the SDK installation be installed on all the client machines? Say, I want to print a very simple label – just a barcode and some text underneath (default colors; 3of9).

  27. Related question: is there a way for Dymo to print directly from .doc (or .docx) as opposed to printing from a .label file? How about from an html div? I noticed my LabelWriter 400 Turbo can print from a .txt file (even though it orients it horizontally by default…)

    • Answering my own question: yes. You simply have to select the correct orientation and paper size from the print dialog in Word. The advanced options for the DYMO printer make this easy.

  28. Hi, when I try out the sample page at http://www.labelwriter.com/software/dls/sdk/samples/js/PrintLabel/PrintLabel.html in IE9, I get the following error when I click the Print button:

    XPath not supported by this browser.: TypeError: Object doesn’t support property or method ‘selectNodes’

    I tried downloading and installing IE9 again but the error remains. Any idea if this is a common issue and so I should not allow IE9 users to try to print labels from my website? Otherwise the JS library works great with all the other browsers I’ve tried. Thanks!

    • OK, there is a problem with IE9. We will look into it but for now you could try following workarounds:

      • Turn on “Compatibility View”. You can access it from Command Bar, Tools menu
      • Instead of calling label.setObjectText() use a label set. E.g. for the sample, the code will be changed from

        label.setObjectText("Text", textTextArea.value);
        label.print(printerName);
        

        to

        var labelSet = new dymo.label.framework.LabelSetBuilder();
        labelSet.addRecord().setText("Text", textTextArea.value);
        label.print(printerName, null, labelSet.toString());
        
      • for more information about label set API see here

  29. I have a question on this example.

    I have successfully altered the original example above to have 6 text fields (all in one row) in a table. The label will print correctly with all 6 fields.

    My question is that I would like to have multiple rows in my table with a print button at the end of each row. Currently when I try to add more rows – only the first row remains functional.

    Any suggestions?

    • Hi,

      It is not clear about what rows you are talking about. Could you be more specific? What is the goal, could you provide a sample data and how it supposed to be printed?

      • The Goal is to have a materials log in sheet with the ability to print off a label as each item is entered. Something similar to a delete row function – where only the chosen row is affected or used when the button on that row is clicked. I plan to have an add rows function to add new blank rows dynamically using javascript – which I have found a script to do so. This is the table structure – only showing 2 rows of possibly many:

        Customer:

        Sidemark:

        Vendor:

        Description:

        Quantity:

        Received On:

        Print

        Customer:

        Sidemark:

        Vendor:

        Description:

        Quantity:

        Received On:

        Print

        As I noted in my first post. I can get one row to work using the original javascript file – adding in my multiple variables instead of just one in the sample. I just don’t see how to isolate one row and send only that info at time of click on the desired row. Possibly load the values from the desired row into an array then load into the javascript function?

        I appreciate any help or ideas you may be able to provide.

      • Thanks very much for the reply, but I’m not exactly sure what you are trying to say. Does that mean you agree with my thought about loading the data into an array first then calling the javascript print function?

        • first, create a ‘print’ function that takes all needed data to be printed as parameters, e.g.


          function printLabel(params)
          {
          var label = dymo.label.framework.openLabelXml(...);

          // set label data using 'params'
          // ...

          // print
          label.print(...);
          }

          in the code that generates rows for the table you can do something like this:


          function addNewTableRow(args)
          {
          // add row elements
          // ....

          // add print button
          var printButton = ;// call dom to create a button element

          // populate needed params for the print function
          var params = {}
          params.firstName = 'John';
          params.lastName = 'Smith';

          // attach event handle that will call print label
          printButton.onclick = function() {printLabel(params);};

          }

  30. I made a kiosk web page and a touch screen when you touch a java enabled object it prints a label file my problem is a 4-5 second delay between touching the screen and printing the label. any idea how to minimize the delay

    • could you provide a code snippet for the printing? As general suggestions:

      – make sure there are no network communication when user clicked the print button. E.g. the label file and all label data should be downloaded already.
      – if printing from Windows, the first print job might take several seconds before actual printing starts. This is because printing system libraries have to loaded. Subsequent print jobs will be fast because the system libraries are in RAM/file cache.

    • what is the delay/time execution for the whole printLabel(id, file)?
      what is the delay/time execution for the the call of label.print() inside printLabel()?

      every tiem printLabel() is called the label file is loaded from “http://localhost/labels/labels/”+id+”.label – this might be a source of the delay.

      as specified in openLabelFile documentation, openLabelFile is not a recommended way to open a label. Try to use openLabelXml() as I used in a original sample for you. Also, openLabelFile will not work if the browser is running on a mobile device, like iPad or Android.

  33. I apologize, Vladimir. Please delete my previous comments. The blog kept filtering it out even when I tried to use the appropriate tags.

    I’m attempting to build a label by hand with XML. It’s working nearly perfectly, except the client reports that the text prints small. I want it print in 18pt size. Am I doing something wrong? Here is my XML: http://snipt.org/xwv

    • try to set TextFitMode to “AlwaysFit”

      what is the text you are trying to print?

      • I will try that, thanks. I’m trying to print fake generated names and addresses, like:

        John B. Doe
        894 Randall Drive
        Honolulu, HI 96819

      • Hey Vladimir, after making the AlwaysFit change, it still prints small. I estimate the printed text to be around 12pt, instead of 18pt.

        Here is the Javascript I’m using: http://snipt.org/xxgn
        Here is the HTML: http://snipt.org/xxgo

        Everything about it works perfectly except the font size. I wonder if it’s something silly, like do I have the font code in the wrong line?

        • seems like there is a empty line in the textarea element. So, you are trying to print four lines, not three one. That is why the text is shrinked.

          Try to remove it, e.g. replace

          Honolulu, HI 96819
          </textarea>

          to

          Honolulu, HI 96819</textarea>

          • Wow, I was surprised that made a difference, but it did. It works now. Thanks Vladimir. I’m grateful!

  34. hello, i’m trying to use the framework behind an authenticated proxy but, on loading the jsp page that use the framework code, i receive error 407 under internet explorer and error calling method on npobject under firefox. the sample page in dym site works well, but i’m just doing the same things! any ideas? thanks a lot!

    • Could you provide more information about your setup? What functions are called by your code, what are the DYMO samples that work for your setup? maybe a snippet of your code that does not work?

      Thanks,
      Vladimir

      • Well, i’m doing some tests, my label has an image and the source is taken from an url pointing to the chart goggle api’s. I need the, to generate a QRCode image. Could be the reference to an external image that is denied from proxy? Searching the forum i discovered the experimental QRCode image, that works well, only i need to adjust the size of the QRCcode, that is too small for the label, i tried the othe sizes bute they have no effects. Are there other parameters that I could use ?

      • Hey Vlad, don’t let me alone!!! ;-)

  35. In the post, it mentions “The easiest way to obtain the xml is to design the label using DYMO Label software, saving it into a file, then pasting file content into the js code”.

    How do you do this?

    I opened my label in the DYMO Label Software 8.0 but there is no Save to XML function. Opening the label file yields a bunch of gibberish.

  36. I work at a Physical Therapy clinic and I use the LabelWriter 400 all the time for printing address’ for statements. Here lately my “address fixer” is not working. It is telling me that there is no internet connection. I am able to get on the internet and look at other sites with no problems though. Anyone have any ideas?

  37. Bottom part of the retour adress is too small. I Have the label above then a line and then an image with my own adress
    My own adress is on one line. I think the problem is how to set a break

    Here my example

    var labelXml = ‘

    Landscape
    Shipping
    30323 Shipping

    Retouradres

    Rotation0
    False
    False
    CenterBlock
    Top
    AlwaysFit
    True
    False

    AFZ. CFpianoservice De oude munt 113 3824 DJ Amersfoort

    Then this is the issue AFZ. CFpianoservice De oude munt 113 3824 DJ Amersfoort

    Should be

    AFZ. CFpianoservice
    De oude munt 113
    3824 DJ Amersfoort

    Thanks for looking in

  38. Hi,

    We have implemented the concept provided above and its working fine.Thanks for the detailed explanation provided.

    We have one small issue like the print that is coming out on the label is of Font Family “Arial”,Size is “10” and it is bold.Customer doesn’t want the text to be in bold font.How to control it so that we will not get the text printed on the label with bold font.

    Here is the JavaScript code written

    var driverlabelXml = ‘

    Portrait
    Small30334
    30334 2-1/4 in x 1-1/4 in

    Text

    Rotation0
    False
    True
    Center
    Middle
    ShrinkToFit
    True
    False

    //
    // Driver Name
    //
    //
    //
    //
    //

    ‘;

  39. I am having a problem getting the actual label to print. I am able to print to the printer using the sample. However, when I put the code into my application I get the printer, label to load and the text assigned to the label, BUT the label.print(printerName) does not print. Any ideas?

    function printbarcode(id) {
    alert(‘test ‘ + barcode.elements[“id”].value);
    // select the first Dymo printer
    var printers = dymo.label.framework.getPrinters();
    if (printers.length == 0) {
    alert(“No DYMO printers are installed. Install DYMO printers.”);
    }
    var printerName = “”;
    for (var i = 0; i < printers.length; ++i)
    {
    var printer = printers[i];
    if (printer.printerType == "LabelWriterPrinter")
    {
    printerName = printer.name;
    break;
    }
    }
    alert("Printer " + printerName);
    // Get label to print
    $.get("Barcode.label", function(labelXml)
    {
    label = dymo.label.framework.openLabelXml(labelXml);

    // Set the label text to print
    label.setObjectText("Barcode", barcode.elements["id"].value);
    // alert("label " + label);
    }, "Text");
    alert('END 11' );
    // Print the label
    label.print(printerName);
    }

    • It is resolved. I had to specify the location before “barcode.label” i.e. $.get(“http://www.xxx.com/Barcode.label”, function(labelXml)
      {

      • What would cause the $.get not to execute? I am now getting “label is not defined” as a popup. It worked for awhile then stopped…….

  40. I am trying to print a 30856 name badge label on the DYMO Labelwriter 400 using the code in this tutorial but it seems like the printer thinks it is printing to an address label… how can I adjust the size of the paper so the printer knows to print on a name badge? Thanks!

    • You can specifiy the label size in your label template (*.label file). Either use DYMO Label Software (DLS) to create your label template or check the following blog posts which are talking about the Label File Format. http://dymodevelopers.wordpress.com/tag/xml/

      • When I attempt to use the tag with 30857, I receive an exception. I’ve only seen examples using “30252 Address” and “30256 Shipping”. I tried “30857 Name” and “30857 Name Badge” and both throw an exception. Any thoughts?

        • You’ll find the form names in the Windows Print Management (Administrative Tools -> Print Management -> Forms). Please try “30857 Badge Label”.

          • Thanks, that solved the problem. Just for my own edification, is that documented somewhere in the API?

            And one other question. Is there a method in the Javascript API to get the dimensions of the selected label?

  41. Does not work in Chrome in 2013

    • I assume you are referring to Chrome on Mac OS X. Now, Chrome version 22 and above have dropped support for Carbon event model of NPAPI plugins. This model event is default for 32-bit plugins and that’s why it can’t load the DYMO plugin. We have to write a new plugin which is anticipated for DLS 8.5.0.

  42. I’m using DYMO LabelWriter 310, in MAC . Safari Version 6.0.1 (8536.26.14).

    Here is the sample code which is as shone above but still “”” I’m not getting the label.print (printerName)”” functionality .
    I’m able to get the printers and their name but ..?

    Here is the code which I have been tried So far,

    function labelprint()

    {

    var label = DYMO.Label.Framework.Label.Open(“squareBrc.label”);

    alert(“Before Text”);

    label.SetObjectText(“NameTxt”, “Ample”);

    alert(“After Text”);

    label.SetObjectText(“CompanyTxt”, “Ample Tech”);

    label.Print(“DYMO LabelWriter 310”);

    }

    //2nd Way

    function PrintLabel1()
    {
    //window.print();
    var labelXml = ‘

    Landscape
    Address
    30252 Address

    Text

    Rotation0
    False
    True
    Left
    Middle
    ShrinkToFit
    True
    False

    ‘;
    var label = dymo.label.framework.openLabelXml(labelXml);
    alert(” “+labelxml);
    var printers = dymo.label.framework.getPrinters();
    var printer=printers[0];
    printerName = printer.name;
    alert(“”+printerName);

    label.setObjectText(“Text”, textTextArea.value);

    // dymo.label.framework.printLabel(printerName, 1, label, label);

    label.print(printerName);
    }

  43. Chrome Mac support please.

  44. How about multiple DYMO printers? I have a DYMO 450 for barcode label printing and a standard POS58 receipt printer. Was not aware the DYMO 450 can print receipts too, so can you install 2 on the same PC and if so, can you change the name it installs under so they can be called separately?

    • Yes, you can install multiple DYMO printers. The names can be change in the Windows “Devices and Printers” window. DYMO is also selling the LabelWriter 450 Twin Turbo which is allowing to print on 2 roles all the time.

  45. Hi, are there plans to implement iOS AirPrinters? Seems these examples do not recognize them?

    thanks!
    Chad

  46. Is there a requirement to also have the .label file on the local machine?

    Prerequisites state that only the DYMO label software be installed on the machine.

    I was able to print labels from my web app on the machine that I used to generate the label just fine.
    It wasn’t until I also placed the .label file on the other test machines that I was able to get it to print correctly.

  47. Hello,

    I developed some software for a client using this framework but he reported me today, it’s no longer working. I’ve tested it myself and indeed it’s broken. I believe the reason is an update to the website. For example: http://labelwriter.com/software/dls/sdk/js/DYMO.Label.Framework.latest.js this doesn’t load any javascript, but it loads a language selector instead…, this is the exact error I get:
    SyntaxError: Unexpected token '<' in ContrySelectorView:1

    I hope this issue will be sorted out soon. Thanks in advance.

    • John,

      Labelwriter.com is currently down. We are working to resolve this issue. We will update the latest blog post when the site is back up and running.

  48. I am currently unable to download the latest javascript file; that URL is redirecting to the dymo home page. Where can I find a copy of the JS to host on my servers? I have an urgent client need to fix it :/

    • Labelwriter.com is currently down. We are working to resolve this issue. We will update the latest blog post when the site is back up and running.

  49. Dear All, May I ask some questions?
    Can Dymo printer installed under Untuntu system,
    Can Dymo support Non-English character ,I will use Chinese to print my label (support under Javascript ? )
    Which Dymo label printer support javascript to print?
    Thank you all

  50. I inherited an old system that uses a .lwl file – which looks to be a binary representation of the badge template. Does Dymo offer a conversion utility to turn that template into XML so I can use it with the java script?

  51. thanks for this library. Still going strong in 2014, in Firefox.

  52. it’s just too bad there isn’t an https server hosting it.

  53. May I ask some questions?
    If there are any java instance to invoke LabelWriter 450 ,not use javascript?

    • I am not a Java expert, but you might be able to invoke JavaScript from Java.

      DYMO is providing APIs for .Net, COM and JavaScript. I guess you could implement a JNI and call the C++ interface from Java. Of course that code wouldn’t be platform independent!

  54. Hi , I have a question here.How can I input image into labelXml? I appreciate.

    • The best approach to your problem is to use DLS to design the label that you want to use. When you save the label file, it will contain the label xml that you want to include in your labelXml variable.

  55. in VisitorManagement example, wherein you can choose template and photos you want to use on the label. Is it possible to setup the printing to be continuous? Because I created a small label and theres no problem with it but it is consuming a long strip. Maybe continuous mode will fix my problem. Is it possible to set it to continuous printing in that example? Thanks

    Heres the link im talking about:
    http://labelwriter.com/software/dls/sdk/samples/js/VisitorManagement/VisitorManagement.html

    • Chris,

      I’m not sure exactly what you are asking, but the Visitor Management example is an example for printing a die-cut name badge label to a LabelWriter printer. This example should not be used to print to a continuous tape printer.

  56. Hi
    I have made changes to the Dymo Web print but am having some issues.

    First issue is when I type into the textarea the text is top left to start with and this is fine. But once I print to a label the text has moved down about 2 rows

    Second issue is there any way in making the printed text fill the whole Label or at least increase the text size

    • Hi Patrick,

      I suggest that you design your label template with DYMO Label Software (DLS), make sure it prints as desired and save it as a template. Then you load the template in your code and just set the object text.

      • Thanks dymodev

        I thought i did that all ready. i must have worked on an old script. as soon as i made the new layout template with the DYMO software my script worked thanks.

        just one question how do i put code onto this website is it code inside on both ends of my code or some other way

        thanks

  57. I am using Polymer for my website and when I try to include the webcomponents.js file (polymer file) with the dymo framework file my dymo code will not work. Returns that there are no Dymo printers installed. If I comment out the webcomponents.js file everything works fine.

    Any reason why the dymo framework script will not function with other javascript files?

    • Hi Tyler, we do not have any experience with Web Components. Have you checked to see if it interferes with any other JavaScript library? There could be known issues with it.

  58. Latest Dymo software will not run after installation.

    • Hi Bill,

      I’m sorry that you are having issues with launch the software. This blog is for helping developers use the SDK that is provided for the printers. If you would please contact: DYMO Customer service at 1 (877) 289-3966, one of our representatives can better assist you in solving your current problem with the DLS Software.

  61. How .lwl file load with the help of javascript?

    I try using .label file but when i upload .label file its not able to pick the .label file & getting error of path.

    please reply asap..

    .

    • .lwl is the old label file extension. .label files should be used. If you open a .lwl file in DLS it will be automatically converted to .label format.

      As for the .label file not being found, sounds like an issue with your server.

  62. how i create label by my own using this API & it returned as XML file as .label file
    so i immediate change font or another content and i get an XML
    please help ,
    this will reduce my lots of work.
    create & modify label without DLS .

    in javascript Or another technology.

    • Creating a label from scratch if not really an option at the moment. Typically, SDK users will create a label in DLS and then allow their users to modify data on the label using the SDK.

  63. Just updated to Os X 10.10.3 in the middle of the night, and suddenly noticed that label printing is not working any more. I can print with DLS but not with this js API.

  64. Thanks a lot, pl! That saved my week :)
    I didn’t even remember, that our application was using external script.

  65. Hi guys

    what is the situation?
    is the labelwriter.com up and raunning or what?
    I my programs sill do not work it keeps showing the error No Dymo printers are installed

  66. Hi All

    I just found out that google chrome is blocking the SDK from running
    and I get No Dymo Printers available java prompt.
    on IE the program works fine.

    I tried instructions here http://developers.dymo.com/category/dymo-label-framework/
    but did not work.

    any suggestions?

  67. Hello, Chrome 45 (expected to be released May 29th, 2015) will drop support for NPAPI altogether. Any thoughts on a work-around? Is Dymo working on support for a newer standard (PPAPI perhaps) or other option?

  68. Hello, thank you for this useful template. I try to read the text to print out of a *.txt file and want to print the read data into a table (or even better an image.bmp). Any suggestions on this?

    read data from txt file -> fit read data into a table (got a label template made by dymo software) -> print table and data

    labelwriter450

    • Johannes,

      Our SDK does not have a “table” object type. You’ll need to, as you mentioned, take an alternate approach.

  69. Thank you drobdymo,

    is it possible to make this table as an image? lets say *.bmp and print the data into this image?

    • Our SDK allows to embed and print an image object, but doesn’t support the generation of an image.

  70. Cant seem to wrap my head around what I am doing wrong..
    I have a asp.net c# web form.
    Created a label using the dymo label maker software.
    saved the label to a local folder.
    If I access it from running in debug mode (localhost) all works fine, as soon as I put it on our test server, it cant find the CoreLabelsm.label.
    I even tried putting it on the server in the project directory and change the file part to point to the server path to the file.
    Can someone point me in the write direction to get it to see the label

    var label = DYMO.Label.Framework.Label.Open(“c:\\repair\\docs\\CoreLabelsm.label”);
    LabelWriterPrintParams p = new LabelWriterPrintParams();
    p.RollSelection = RollSelection.Auto;
    label.SetObjectText(“Text”, “test”);
    label.Print(“DymoLabelParts”, p);

    Thanks for any help or suggestions.

  71. i´m getting the following error
    ExceptionType: “DYMO.DLS.Runtime.DlsRuntimeException”
    Message: “Unable to load label template”
    StackTrace: ” at DYMO.DLS.Runtime.Label.Load(String uri)
    ↵ at DYMO.Label.Framework.Label.Open(String uri)

    i´m using

    string uri = HttpContext.Current.Server.MapPath(@”~/TempF/PlantillaQR.label”);
    var label = DYMO.Label.Framework.Label.Open(uri);
    label.SetObjectText(“txtReferencia”, “”);
    label.SetObjectText(“Barcode”, obj[i].Tr_Barcode);
    label.Print(“\\\\mam05jsc\\DYMO LabelWriter 400”);

    i check, the label is in the path, and the application has all the permissions

    what can it be?
    thanks for your help

    • Does it work when loading the the .label file form local drive? Make sure that the returned uri string isn’t a null reference.

  72. Hi ,

    I have a really frustrating problem with numerous DYMO labellers that prints out a blank label in between each good one. I’m using the latest driver’s v8.5.1. I’m trying to print from a third party vendor application written in C#, with a windows OS platform ( This problems exists in XP and 8.1). The application works fine when connected as the default printer, but the problem seems to originate when the dymo printer is not connected as the default printer and a network printer is the default printer. Is there something I can do code wise in the DLS or a simple fix.

    • Hi Dan, This could be caused by a number of issues:
      1. The paper size for the label that is being sent to the printer is larger than the paper in the printer.
      2. The printer could need to be cleaned, something could be blocking some of the internal sensors.
      3. Some third party manufactured labels could cause this issue.
      4. There could be an issue with the third party vendor application. You could try one of the samples contained within our SDK Samples and documentation and if the sample works then you will need to contact a representative from the vendor that provided the application.

  73. For some reason, the printer is not being detected. I’ve tried different browsers.

    This is the code –

    function loadText() {
    var labelXml = ‘LandscapeAddress30252 AddressTextRotation0FalseTrueLeftMiddleShrinkToFitTrueFalse’;
    var label = dymo.label.framework.openLabelXml(labelXml);
    var labelSet = new dymo.label.framework.LabelSetBuilder();
    var record = labelSet.addRecord();

    var textMarkup = ‘$text$’;
    record.setTextMarkup(‘Text’, textMarkup);

    var env = dymo.label.framework.checkEnvironment();
    var printers = dymo.label.framework.getPrinters();
    var printerName = “”;

    if (printers.length != 0) {

    for (var i = 0; i < printers.length; ++i) {
    var printer = printers[i];
    if (printer.printerType == "LabelWriterPrinter") {
    printerName = printer.name;
    break;
    }
    }
    }

    label.print(printerName, null, labelSet.toString());

    }

    function frameworkInitShim() {
    dymo.label.framework.init(loadText); //init, then invoke a callback
    }

    • Hi Jim,
      What version of DLS do you have installed on the client machine? What OS is the client machine? Can you print a label from DLS on the client machine?

    • Hi Jim,
      did you solve your issue? I have the same problem!

      On this line:
      var printers = dymo.label.framework.getPrinters();
      I got “null” are return value :(

      Regards,
      Marco

  74. Can you show an example of connecting to the print server when it’s on a different subnet?

  75. Hello! Great post!
    From some days this line of code does not return the printer:

    // select printer to print on
    // for simplicity sake just use the first LabelWriter printer
    var printers = dymo.label.framework.getPrinters();

    Could you help me?

    Regards,
    Marco

    • I assume that you are using “DymoLabelFramework”, Try this sample code.

      // clear all items first
      LabelWriterCmb.Items.Clear();

      foreach (IPrinter printer in Framework.GetPrinters())
      LabelWriterCmb.Items.Add(printer.Name);

      if (LabelWriterCmb.Items.Count > 0)
      LabelWriterCmb.SelectedIndex = 0;

      LabelWriterCmb.Enabled = LabelWriterCmb.Items.Count > 0

  76. The solution also not works for me.
    -> If you take the Firefox, then you will be asked for calling the Funktion. –> Firefox works

    -> Chrome ist not working.

  77. Can we use this library for star printer as well ?

    • Could you elaborate a little bit more on your issue? What DYMO Label Software (DLS) version are you using? Where is the printer attach (client/server)? How are you sharing the printer? How does the client access the printer? Are you able to print from DLS from the server and client? Are you using your own application for printing? Are you using the the DYMO Label Framework?

  79. Hi, I’m completely new to this and got my first Dymo printer yesterday. It’s a LabelWriter 450 and I have installed it with the latest version of DLS for Windows 8.5.3 (I’m running Windows 8 btw). I downloaded and tried this example locally but with the 2.0.2 version of the javascript framework (downloaded locally as well).

    It works in both Chrome and Firefox but it is extremely slow. It takes up to a minute to get the label printed. Looking at the network tab in Chrome developer tools it seems like GetPrinters is the main problem. In my last attempt to print it had a Waiting (TTFB) of 53.04s so it seems like it’s the web service that is slow.

    What can I do to speed this up? Printing from the actual Dymo Label application is lightning fast.

    • Some additional findings. I simplified things to just this:

      function PrintLabel()
      {
      var label = dymo.label.framework.openLabelFile("D:\\temp\\dymo\\Badge.label");
      label.setObjectText("txtName", "John Smith");
      label.setObjectText("qrData", "55224499");

      label.print("DYMO LabelWriter 450");
      label.print("DYMO LabelWriter 450");
      }

      Apparently label.print also calls Get Printers and the interesting thing I find is that with two label.print after each other the first one is still slow but the second one is fast resulting in a waiting time of usually 53 seconds and then both tickets are printed. The second GetPrinters call only takes a few milliseconds. If I trigger the function again it’s the same, first call slow, second one fast.

      • The web service attempts to bind to a port within a range of 10 ports starting with “41951”. I am wondering if you are using the the last one of the 10 ports which the web service attempts to bind.

        The port can be configured. Could you please use “configure” to see what port that it is bound to. You might try to use a different port and check if it has an impact on the delay.

        • Thanks for your reply. I checked, and it uses the first port 41951.

          I tried downgrading to 8.5.1 and the beta2 of the web service and js with no difference. I also tried uninstalling and reinstalling the whole thing, still the same. BUT when I installed it on an older Windows 7 machine it worked perfectly. But I still want to know what is happening and fix it so I can use my regular computer and be sure it doesn’t happen when I install it on other computers later.

          Are there any logfiles saved anywhere that can help troubleshooting?

          • There seems to be a problem with web service discovery, and once it is discovered, everything runs smoothly.
            If it runs slowly in both browsers, this is most likely system-wide problem, for example some software (like antivirus or firewall) interferes with service work. Please disable antivirus and/or firewall and see if it helps.

            Could you please provide the following information:
            1. OS version, 64- or 32bits
            2. Firefox and Chrome version
            3. Third-party software with versions that may interfere (system-related, like antivirus, and network-related, like firewall).
            4. Web service log: %LocalAppData%\DYMO\DLS8\DLSWebService.log (it is recommended to delete existing log before making a test run, so it will contain only relevant recent messages)
            5. Enable web service tracing (by setting dymo.label.framework.trace = true; before calling dymo.label.framework.init()) and provide browser’s console output.
            6. Open developer tools in browser(usually by pressing F12), go to network section and run the tests with network window open, then make a screenshot to analyze network activity.

          • I tried disabling the firewall, antivirus is managed on a domainlevel so I can’t disable that, but on the other hand the other computer where it is working is connected to the same domain and has the same antivirus. Also I’m not sure it has to do with web service discovery because StatusConnected runs fine in a few ms and then it hangs on GetPrinters almost always for 53.0X seconds.

            1. Windows 8 64 bit
            2. Chrome 47.0.2526.111, Firefox 43.0.4, Internet Explorer 10.0.9200.17607
            3. Windows Firewall and System Center Endpoint Protection
            4. This is the output I get from the code above. Please note the 53s gap between the first GetPrinters and the first PrintLabel and compare it to the gap between the second GetPrinters and the second PrintLabel:

          • Hi Niklas,
            This is the first that we’ve heard of such a delay. If understand correctly, you have only have one machine that exhibits this issue? It strikes me as a machine related issue but I will forward this to the developers and see if they have any ideas.

          • I also ran into the same issue “Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user’s experience. For more help, check http://xhr.spec.whatwg.org/.” when setting up my printer to print on demand from my HTML page. What I ended up having to do is separate the load printer and print to printer functions instead of loading the printer in the same function that prints…

            var printerName = "";

            function load_dymo(){
            var printers = dymo.label.framework.getPrinters();
            if (printers.length == 0) throw "No DYMO printers are connected. Install and connect a DYMO printer.";
            for (var i = 0; i 0){
            var l = dymo.label.framework.openLabelFile("/dymo_layouts/barcode.label");
            l.setObjectText("BARCODE", barcode);
            l.setObjectText("TEXT", description);
            l.print(printerName);
            } else {
            alert("Unable to Print Barcode!\nPlease connect DYMO printer first.");
            }
            }

            ————————–
            In my header file :
            ————————–

            $(window).load(function() {
            load_dymo();
            });

            Hope that helps!

  80. Hi! I am using this API for printing labels and it works great!
    My question though is, how can I export the generated labels to PDF?…

  81. I’m having an issue with vertical aligning label text for a twin turbo roll printing on the right side. My XML works fine when I print on the left, but if I print from the right the text is aligned to the very bottom instead of in the middle. Any idea what’s going wrong here?


    var text = "Testing";
    var labelXml = 'LandscapeAddress30252 AddressTextRotation0FalseTrueCenterMiddleAlwaysFitTrueFalse'+text+'';
    var label = dymo.label.framework.openLabelXml(labelXml);
    label.setObjectText("Text", text);
    var params = dymo.label.framework.createLabelWriterPrintParamsXml({twinTurboRoll: dymo.label.framework.TwinTurboRoll.Right});
    label.print(printerName, params);

    • Have you loaded 30252 address labels on both sides of your Twin Turbo printer? Does it print correctly when loading your .label file in DYMO Label Software (DLS) and print to the left as well right? Are you able to duplicate with the DYMO Label Framework C# Sample which is shipping with the DYMO SDK?

      • Im facing a similar issue on Label Writer 450 Twin Turbo. I have the print params configured to the Right side, however while initiating the print it prints on the both side. While doing the same on the Left side, it just works as expected (Only on the left side).

        var printParams = {};
        printParams.copies = 1;
        printParams.TwinTurboRoll = ‘Right’;
        printParams.printQuality = ‘Text’;
        printParams.jobTitle = ‘Large Label’;

        Any thoughts on how to fix the issue.

  85. Is there an answer yet for printing from iPad to LabelWriter (450 Turbo specifically, but if not any other possibilities)?

    • Our SDKs do not currently support printing from mobile devices. We’ve had several customer’s create proxy services their mobile apps can talk to work around this implementation, but our SDKs do not support mobile printing natively.

    • I am not sure I understand your question.
      You certainly don’t need to program a button to print a label, you can code it however you would like.

    Wondering if you guys are any closer to using JSON?

  93. I’m researching the available options for adding label printing to a 450 Turbo from a PHP web application we’re building. We need to print single and bulk labels from a backend database. Can someone please point me to any web sdks – I’ve downloaded and installed DYMO-Label-v.8-SDK.dmg but that just appears to have some AppleScript examples which I don’t believe are helpful for printing from Safari (we’re all Mac based). Any documentation for any web SDKs would be great as well.

      • I am happy to help you with any issue you are having with the SDK. Unfortunately, I am not a javascript expery. I would assume you could use a page_load event or something similar.

  96. It seems to stopped working in Firefox around version 56.0.2
    It doesn’t work on http://www.labelwriter.com/software/dls/sdk/samples/js/PrintLabel/PrintLabel.html nor at my website.

    However it works in IE, so there is something with the browser.
    Will there be a update that make it compatible with FF again?

  97. How would you go about having 2 print buttons on a single page, with each button printing to different labels? Have tried loads of things but can only ever get the first one to fire, the second button does nothing.
