if I write system-config-printer in the debian template I get the expected GUI to config the printer and everything works as expected.
If I write the same in the VM depending from the template, I get:
Printing service not available. Start the service on this computer or connect to another server.
If I click on start the service, nothing happens.
After many years using Qubes, the template and the VM depending from the template always behaved in the same way. I cannot understand why the template works and the VM does not.
To be sure, I tried on two different VMs depending from the same template an none works
