I am experiencing the same on my A04.
Also switched from repo version to snap version to see if it’ll run smoother.
You can fix your printer by adding an apparmor rule (it’s what disables the printer).
However the problem I am having is, that the gamepad controls aren’t picked up in the snap RetroArch. They worked perfectly fine in the repo version.
