Hello Mr. Kamppeter,
we ran the commands and experienced the following:
1. no job in queue -> AppArmor was running -> killall = cupsd crashes
2. 20 jobs in queue -> AppArmor was running -> killall = cupsd crashes
3. no job in queue -> AppArmor was stopped -> killall = cupsd crashes
4. 20 jobs in queue -> AppArmor was stopped -> kilall = cupsd crashes
This are the system messages for point 1) and 2):

We tried to run the system without AppArmor today, but we experienced
the usual hangup of cups at 8:40 AM. Hope that helps.
