I resolved the problem by installing Gutsy on another PC. After the installation of the Lexmark drivers I went to System -> Administration -> Printers to add the printer, and noticed that there were TWO drivers listed:
1. Lexmark Z600 Series USB #1 Device URI: usb://Lexmark%20/Z600%20Series 2. Lexmark Printer Device URI: z600:/dev/usb/lp0 Driver 1. does not work, driver 2 works. Going back to first PC and changing driver to "Lexmark Printer" results in being able to print. -- [GUTSY] Third-party drivers (like Turboprint) do not work due to AppArmor https://bugs.launchpad.net/bugs/133818 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
