Dymo 450, Error The 'DesktopLabel' is not declared

[ValeskaBotha]

Good day, I want to find out what this error means: The 'DesktopLabel' is not declared

Setup: Dymo 450 twin printer, Using angular interface, Web service running, standard port

On client's machine: When selecting to find printer - the printer is selected and displayed. When selecting to print the label with data - it returns error about the DesktopLabel not declared.

On my local machine, and 2 other persons PC's - We use the same application and same 2 label templates and both work.
But on the client's machine we get this error.

What we found in the past is - that if I create the label - the other person cannot open/view it. If the person creates it on his machine - I cannot view/open it But if I use the template (he created) and print it via the web app from my or his machine - it will print it correctly without any errors.

What I also found is the difference in the xml: <?xml version="1.0" encoding="utf-8"?>

DYMO Label Landscape Address1982991 DYMO Label Landscape Address30251 Can you advice? We need to use the angular web application on the client's machine.

Very recently I have started receiving similar error - but instead of DesktopLabel, I get DieCutLabel is not declared.

It used to print it fine - Don't know what changed. I also tried the sample code from here - and I get exactly the same error.

It turned out that there was both a Dymo Label v8 and Dymo Connect installed both on the same machine - so it was clashing. When existing Dymo Label v8 Web service - the issue was resolve and we where able to print.
