In a previous post we looked at the new label file format used by DYMO Label v.8 software (DLS) from a bird’s eye view. Now it’s a time to look a little closer. The most important thing in a label file are label objects. Label objects contain data and formatting properties and define the label’s content. All object types and most of their properties are available through the DLS UI and are pretty straightforward. In this post we will briefly describe all label objects and will  look at most important properties as well as at properties not available through the UI.

Let’s look at  this label file. It contains all the different object types supported by DLS. If you open the label in DLS it will look like this:

Common Properties

011             <Name>BarcodeText</Name>

Name is one of the most important properties. It serves as a unique identifier for an object. Usually it is used to refer to the object from code that uses the DYMO Label SDK. There are no restrictions how to name the object. The name can contain any Unicode character and the name length has no limit. Still, it is a good practice to only use alpha-numeric characters and keep the name length short. It is not required to assign a name to the object – if the object is not going to be referenced it is perfectly OK to have empty name. It is also OK (but not very useful) to have two or more objects with the same name. The DYMO Label Runtime will use the first object found with a specified name. There is no guarantee which object with the same name will be used. Names are case sensitive, so “Name”, “NAME”, and “name” are treated as different names.

128         <BarcodeObject>
129             <Name>Barcode</Name>
132             <LinkedObjectName>BarcodeText</LinkedObjectName>

LinkedObjectName property defines a link where you can content from a different object as content for the current object. For example, look at line #124. It specifies that the text for the barcode object named “Barcode” should be taken from an object named “BarcodeText”. In the DYMO Label application it is only possible to link a barcode object to a text object. But in code it is possible to link any objects by specifying LinkedObjectName property directly in the label file.

517         <ImageObject>
518             <Name>Graphic-Clone</Name>
521             <LinkedObjectName>Graphic</LinkedObjectName>

Line #432 directs the Runtime to get image data for the graphic object named “Graphic-Clone” from the graphic object named “Graphic”. As a result the label file contains only one copy of the image data: that significantly decreases its size.

Text Object

The Text object displays a block of text.


The StyledText property specifies the object’s text and text style(s). the following attributes are available on a per character basis:

  • font name
  • font size
  • font style: bold, italic, underline, strikeout
  • color (character foreground color)
066             <StyledText>
067                 <Element>
068                     <String>DYMO
069 </String>
070                     <Attributes>
071                         <Font Family="Arial" Size="12" Bold="True" Italic="False"
072                                      Underline="False" Strikeout="False" />
073                         <ForeColor Alpha="255" Red="0" Green="0" Blue="0" />
074                     </Attributes>
075                 </Element>
076                 <Element>
077                     <String>828 SAN PABLO AVE
078 </String>
079                     <Attributes>
080                         <Font Family="Arial" Size="12" Bold="False" Italic="True"
081                                      Underline="False" Strikeout="False" />
082                         <ForeColor Alpha="255" Red="0" Green="0" Blue="0" />
083                     </Attributes>
084                 </Element>
085                 <Element>
086                     <String>ALBANY CA 94706-1567</String>
087                     <Attributes>
088                         <Font Family="Arial" Size="12" Bold="False" Italic="False"
089                                      Underline="True" Strikeout="False" />
090                         <ForeColor Alpha="255" Red="0" Green="0" Blue="0" />
091                     </Attributes>
092                 </Element>
093             </StyledText>

The example above specifies that the text contains three lines, with each line formatted differently. The Element tag specifies a range of characters with the same formatting. The String tag specifies text/characters, while the Attributes tag specifies text formatting attributes.

Adding Line Breaks

To include a new line separator just put a new line/carriage return symbol(s) into the String tag. The text specified by above StyledText will be displayed like this:

ALBANY CA 94706-1567
021             <UseFullFontHeight>False</UseFullFontHeight>

The UseFullFontHeight property can be used to increase font size to the maximum possible size when shrink-to-fit or auto-fit are applied to the object. When UseFullFontHeight is True (the default) the line height is calculated based on the font metrics. So, the height is the same regardless of the text content. When UseFullFontHeight is False the line height is calculated based on the height of each character’s “black box” (an area where glyph outline is drawn). Because usually a character’s “black box” height is smaller than its font height a bigger font size can be used to draw text.  This property might be useful in scenarios where printable area is limited but you want to make the text as large as possible, e.g. for tape labels. For example, below is the same label with only UseFullFontHeight property changed.

Address Object

The Address object is similar to the Text object. It is used to display address information. If the address is a valid US address then the Address object can also display and Intelligent Mail barcode.

Barcode Object

The Barcode object is used to display barcodes on the label.

Image Object

The Image object is used to display bitmap images on the label.


The Image property specifies image data. Image data is encoded using base64 encoding and the image data itself is in PNG format.

544             <ImageLocation></ImageLocation>

The ImageLocation property is another way to specify image data. In this case image data is not stored inside the label but is loaded on demand from the specified URI. The URI can be a path to a local file, e.g. “C:UsersUserNameDocumentsMyImage.png” or “http://”, “https://” or “file://” URLs. The URI can point not only to PNG files but to any image file type supported by the DYMO Label Software (BMP, JPG, GIF, TIF, PNG). ImageLocation can be used in scenario when there is a set of label files that should share same image, e.g. a company logo.

Note: the specified URI will be accessed on demand, basically when a label is being printed or previewed. If the URI specifies a remote resource there can be a delay or even an exception if the URI is inaccessible.

Date and Time Object

The Date and Time object is a special kind of the Text object designed to display current date and/or time.

Counter Object

The Counter object is a special kind of the Text object designed to print auto-incremented numbers. Every time the label is printed the Current property of the Counter object is updated based on the Increment property. So, the next time the label is printed the new updated value for the Counter will be used.

Note: To preserve the value Current property between an application runs (so, the next time application runs the Counter continues from its last value), the label should be saved when the application exits. To avoid unnecessary label modifications we do not recommend to use Counter objects in SDK applications. Use Text object instead and format its text according to the application’s logic. The “current” counter value can be fetched for example from a database or from a web-server in a way the application fully controls and understands.

Shape Object

The Shape object displays simple geometric figures like rectangles and ellipses as well as vertical and horizontal lines.

Circular Text Object

The Circular Text object display text on a curve. Usually it is used on CD/DVD labels.

  1. Hi,

    How can I add a line break to a tape label at run time in javascript code ?
    I would like to have my text on 2 lines.

    • Hello Yves,

      Unfortunately, text object does not support word wrapping. So, the only choice is to manually separate the text to multiple lines.

      This might be tricky. If your application uses a predefined label layout/file(s), then the simplest way is to open it in DYMO Label software and to estimate how many characters are fit in one line by just typing into the desire field(s) on the label. Knowing the average number of characters per line you will be able to split the input string into multiple lines. It is not necessary to know the exact layout for the text, because shrink-to-fit will do necessary shrinking if needed (it is even better to use ‘always-fit’ setting, so the text can be enlarged as well).
      If your application can print any label (a label somehow specified by a user) then you could use low-level API to get the object’s dimensions (using ILabelObject.Width and/or ILabelObject.Height) and object’s font information (using ITextObj.TextAttributes.Font_1 and ITextObj.TextAttributes.Font_2). Knowing these values you can calculate average chars per line using Win32 API or .NET text measuring functions.
      Both of these methods are not ideal, but there is no other way.

      • Hi Pi,

        Thanks for your quick answer.
        The layout of my label is predefined : 1 QR-code + 2 lines, 1 with a text and the other with identifiers (1234 – 21 for example).
        In my web application, I load a javascript where my Dymo label is defined within a variable :

        var rubanXml = ‘\
        \ …

        To define multiple lines in the Dymo label XML, it is a CR + line feed at the end of the text :


        but it does not work inside a javascript variable.
        I have tried the escape notation, the but it does not work.
        Do you know which notation or code I have to use inside my javascript variable for the CR + line feed ?
        Thanks in advance.

        • Sorry, code has disappear from my post due to XML notation but it is only the standard XML structure of a DYMO label

        • Just put a new line/carriage return into the String tag to include a new line separator. Please see above under “Adding Line Breaks”

  2. Is there a way I can use the counter object to append an incrementing count onto another variable?

    label 1 – abcd_1
    label 2 – abcd_2
    label 3 – abcd_3

    This will be represented as a barcode so it is important the incrementing count is appended to the end of the variable and not be a separate value.

    We will print dozens of labels at a time so I would like to avoid having the application handle this which would require multiple print commands and slow things down.

    Thank you

  3. Is there any way to convert this XML to post script?

    I’m trying to generate the label using a web application, and would like to be able to submit it directly to a label printer. In my case, i’m using the LabelManager PnP wireless.

    In particular, I’m building an inventory tracking system that needs bar codes generated for each inventory. I am currently using the XML format with the code128 auto type supported natively by the dymo printer.

    Ideally, i’d like to be able to visit my web application, hit print, and have the label print from the dymo printer. If possible, I’d like to do this from iOS, like an iPad or iPhone, without having to install any additional software.

    I’m willing to set up some kind of proxy service for the printer if necessary, and am considering the CUPS driver for linux. I was considering running an air print / bonjour proxy from something like a raspberry pi, so that my iOS device can discover the printer and print to it this way.

    Here is a sample XML document: which uses the native bar code rendering (which seems to be quite good). If I must, I can generate any file necessary on the server side to send to the printer, including a post script file.

    Any advice?

  4. Is there any way to scale the BarcodeObject of Type “QRCode”?

    The Size “Large” setting is not enough. The rendered code is too small.

    • Hi Simon,

      Sorry, there is not. You might try creating an image that is your barcode and the image to your label, but we cannot guarantee the barcode scanners would work as well. But, worth a try.

  5. Is there a way to set the ImageLocation via JavaScript?

  6. Your documentation above says “Adding Line Breaks – To include a new line separator just put a new line/carriage return symbol(s) into the String tag.”

    I’m pulling data from a web service, and doing something like below. Can’t seem to get a line break/carriage return to work. Any tips?

    var labelXml = ‘LandscapeAddress30252 AddressTextRotation0FalseTrueLeftMiddleAlwaysFitTrueFalse’;
    var label = dymo.label.framework.openLabelXml(labelXml);
    var str = data.d;
    //str = str.replace(“|”, “”);
    label.setObjectText(“Text”, str);
    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 =;

  7. I ask a legit question about inserting a new line/carriage return into an label object via the javascript library, it says ‘waiting for moderation’ or something for a day or 2, then the question disappears and no response?

    • Sorry, Nolan. I was out of the office when you posted and unable to moderate your post. I have since responded to your inquiry.

  8. Is there someplace that I can view complete documentation for the xml to see what all the settings/options are and what they are use for?

  9. how to print such xml file via c # with 5 copies?
