Working with DYMO Label Web Service
What is the DYMO Label Web Service?
In the past, developers had to provide a browser-specific plug-in for each major web browser. Nowadays, most browsers have phased out native plug-in support. Google, for example, stopped supporting Chrome their NPAPI browser extension in September 2015. In response, we released the DYMO Web Service as a new cross-browser solution allowing third-party developer applications the ability to interface with the DLS SDK in a seamless, browser-agnostic fashion. It handles all printer-related requests from the JavaScript Library that the DYMO Label Framework browser plug-ins used to perform.
How can I tell if the DYMO Label Web Service is running?
You should see the DLS application icon within the system tray. Right-click this icon to display a context menu. The menu displays the web service’s status (i.e., “Started on port 41951” or “Stopped”).
The following shows what it looks like on Windows.

How can I start the DYMO Label Web Service?
If your DYMO Label Web Service does not say Started on port: port # within the 41951-41960 range, your Dymo cannot connect to the Internet browser. You can start the web service at any time by right clicking on the service’s icon in the system tray and choosing the Start service menu item.
How can I configure the DYMO Label Web Service?
Clicking the Configure menu item will cause a configuration window to appear. This allows you to change the language and listening port. The web service will normally try to use the first available port within the 41951-41960 range. You can override this behavior by checking the Use single port checkbox, which makes the service only try using the specified port only. You cannot specify a port number that does not fall within the specified range. The service will not try using any other port if an error occurs while using this option.
