As usual, submitting to early, trying again ...
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
sudo aa-complain cups-browsed
To return to the standard settings do
sudo aa-enforce cupsd
sudo aa-enforce cups-browsed
Is your printer discovered and can you print on it with AppArmor
enforcement de-activated on CUPS and/or cups-browsed?
