You can start or stop the web service at any time by open right clicking on the service’s icon in the system tray and choosing the Start service and Stop service menu items, respectively.  Although API functions will not execute after stopping the service, the service icon will remain in the system tray after stopping it.

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.
