But now I would like to impose on your good will. I do not know if you are aware of it, but apparmor has been activated as an experiment in buster to see if it would be suitable in a stable release. Would you reinstall it and look for "audit" in journalctl or syslog when your printing fails and the connection to localhost:631 resets. It would be useful for us to have any error messages. Cheers, Brian.
