I run into a problem when printing labels (product labels, serial number labels, packaging labels).

When i setup the report to the right printer in the IOT module, i can print a label once. 
The next time i want to print a label, i can click the button in the selection screen for the format, but nothing happens.

Then i go into the IOT module and delete the link for the printer and after this i can print again, once.

Does someone know the answer to this problem?

I asked Odoo tech support 2 days ago, but i did not get respond yet and cannot find the solution anywhere...

Thanks in advance for help or tips.
