The permissions and ownerships of /dev/usb/lp0 are correct. Permissions and ownerships of symlinks have no meaning, always the permissions and ownerships of the physical file count.
It seems that there is a problem with printing through the usblp kernel module. This would be a kernel problem. Please check whether the PPA solves the problem. Please update all the 11 files you get offered. My PPA carries only printing-related packages and for Oneiric I have only uploaded cups and cups-filters AFAIR. The packages are all the binary packages of the source packages cups and cups-filters. After installing the PPA unplug the adapter cable from the computer's USB and plug it back in again while the printer is connected to the parallel end and turned on. Do you get a print queue auto-created now or at least system-config-printer popping up and asking you for manual make/model selection? Does the command sudo /usr/lib/cups/backend/usb detect a USB printer, your adapter cable, an unknown USB printer, ...? This is your BJ-200. If no working print queue gets auto-generated, open system-config-printer, click "Add", choose the local USB printer entry (BJ-200, your adapter cable, or Unknown) and manually choose manufacturer and model if needed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/938640 Title: canon bj-200 has stopped printing To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/938640/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
