This looks like that either AppArmor got more restricted in Jammy. I
will CC AppArmor folks to make them aware, but due to the holidays they
will possibly not react quickly. So I recommend to temporarily de-
activate AppArmor for CUPS and for cups-browsed:
sudo apt install apparmor-utils
sudo aa-complain cupsd

Title:
Driverless printing detection does not work
Status in apparmor package in Ubuntu:
Incomplete
Status in cups package in Ubuntu:
Incomplete
Bug description:
20 Dec 2021 fresh just installed ubuntu budgie jammy daily
My network HP Photosmart printer is not detected. In fact the only
printer found via gnome settings is CUPS-BRF-PRINTER
This is a regression since both 20.04.3 and 21.10 both find the same
printer on the network automatically.
