Aurimas, can you do the following additional tests: Update to cups 1.5.3-0ubuntu2~ppa13, make sure that the usblp module is not blacklisted and that the module is loaded. Turn off your printer and turn it on again.
Now run lpadmin -p <queue> -o usb-no-reattach-default=true to make the USB backend not reattach the usblp kernel module after a print job. Does this solve your problem? Try with both Plug'n'Print active sudo chmod +x /lib/udev/udev-configure-printer and suppressed sudo chmod -x /lib/udev/udev-configure-printer Get back to the old state via lpadmin -p <queue> -R usb-no-reattach Always replace "<queue>" by your print queue name. Try also manually reloading the usblp module via "sudo rmmod usblp; sudo modprobe usblp" after a job has completely finished (all pages have come out) and before sending the next job. -- 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
