I think this might be a problem with apparmor. From https://wiki.ubuntu.com/DebuggingPrintingProblems
>From Gutsy on the security of the CUPS printing system is improved by using AppArmor. Unfortunately, the configuration is not perfect yet, especially if third-party printer drivers are used. If you have any problems with printing, try deactivating the AppArmor protection with sudo aa-complain cupsd. If this helps, look for messages containing audit in the /var/log/messages file. These show which components are accessed by the printing system for which there is no explicit permission given in /etc/apparmor.d/usr.sbin.cupsd. You can re-activate AppArmor via sudo aa-enforce cupsd. Report a bug (package "cupsys" so that we can correct the default configuration of AppArmor. Could you try that and see what happens? ** Changed in: cupsys (Ubuntu) Status: New => Incomplete -- ubuntu 7.10 on pen4G, cups update problem https://bugs.launchpad.net/bugs/183028 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
