Comment 9 for bug 2025526

Hi,

I have the same issue as well, on two different boxes (ubuntu 22.04) with two different printers (HP & Samsung).

The printers show up in "system" settings. The Firefox snap is able to print correctly, it is connected to cups-control (not cups as the Chromium snap).

Here's the relevant outputs:

------------------------

user@box:~$ lpstat -v
device for HP_DeskJet_3630_series_91ACE7: implicitclass://HP_DeskJet_3630_series_91ACE7/
user@box:~$ lpstat -p

user@box:~$ cups.lpstat -v

------------------------

I have setup native cups in the distant past in large enterprise networks, but the snap plug-slot system is new to me. I'm happy to help fix this. Please let me know if you need any further info or assistance.

Cheers
