Hi, By looking at the syslog it seems that cupsd is replaced by apparmor_parser.
******************** Sep 4 23:11:03 ybear kernel: [51802.712433] type=1400 audit(1315195863.482:27): apparmor="STATUS" operation="profile_replace" name="/usr/sbin/cupsd" pid=23455 comm="apparmor_parser" ******************** Can you stop apparmor service and then try to print again???
