[Trisquel-users] Add new printer: "could not add new printer" error message

[louis . rouille]

Hi there,
I try to get a printer work with a Trisquel computer. When I go to the system  
settings, printer and try to add a new printer: I can see the printer I want  
to add, so I select it and click on "add this new printer". Then it says  
"could not add new printer", without telling me more.

I am pretty sure it is not a driver problem, since I have another computer  
running on Debian Stretch with the same drivers installed on both computers.

I don't quite get how to solve the pb, nor how to get some more information  
about it. What can I do?

Best,
Louis
