Sorry for the late reply. I have checked your error_log now and according to it the USB backend does its part correctly. Now one can see how the driver establishes a dialog with the printer through the backend. The segfault looks like a bug in the Lexmark driver for me. I have also established a dialog between driver and printer with /usr/lib/cups/filter/commandtops (PostScript printer maintenance driver) and a PostScript printer.
Perhaps the Lexmark driver is missing some error handling and robustness against timing deviations. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/902535 Title: Unable to print to Lexmark S405 since upgrade to 11.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/902535/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
