To display /var/log/syslog, open it with an editor, or run less /var/log/syslog
Then search for "audit" lines in the file. If you run grep audit /var/log/syslog only the "audit" lines are displayed. Please post these lines here. For the second part, run sudo apt-get install apparmor-utils and after that cancel -a sudo aa-complain cupsd Try to print again.
