The Epson AcuLaser CX11 indeed needs a manufacturer-supplied proprietary driver. It does not work with any driver which comes with Ubuntu.
Everyone who has another printer, please report a separate new bug (if you have not done so already). Assign it to the "gutenprint" package and proceed as described on https://wiki.ubuntu.com/DebuggingPrintingProblems, especially supply an error_log as described in the "CUPS error_log" section. Before starting to do any investigations on your system to obtain the error_log or other information, please do a full system update as some printing-related bugs got fixed by recent updates. Closing this bug as it was opened on a case of an unsupported printer. ** Changed in: cups (Ubuntu) Status: Incomplete => Invalid -- Epson AcuLaser CX11 printer won't print (Lucid) https://bugs.launchpad.net/bugs/569190 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
