Aurimas, thank you for your testing. Now please do the following: sudo apt-get install system-config-printer-udev
If the system tells you that the package is already installed do sudo apt-get install --reinstall system-config-printer-udev Make sure that the kernel module is not blacklisted and loaded. Turn off and turn on the printer. Work with lpadmin -p <queue> -R usb-no-reattach Now do test jobs again. DO NOT do "sudo rmmod usblp; sudo modprobe usblp" between successful jobs, do it only after a job which failed. The difference to the previous test is mainly that you know will work with Plug'n'Print activated. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/997040 Title: usb printer backend hangs when usblp kernel module is loaded To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/997040/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
