It look like "/usr/lib/cups/backend/hp" backend is failed to open device and exit with status 21. Up to i know "SELinux" is also in disable state in ubuntu. Printing has been working before upgrade and also with different version of Ubuntu. I guess "hplip" package has no changes with this upgrade.
Workaround: Adding printer from CUPS web interface. http://localhost:631. So, CUPS will use "usb" as backend for communication. Once if we get "/usr/lib/cups/backend/hp". we need to restart the machine. /usr/lib/cups/backend/hp uses libusb API calls for USB communication with printer. "/usr/lib/cups/backend/hp" code is same/common for all the HP printers (device independent), . Can any one run "hp-makeuri" and attach the output. Wim Cools, hp-check log showing that your system is using "hpcups" filter and using "hpijs" ppd for printing. Can you please remove printer queue and re-add it. It looks like some issues with 2.6.32-22 and 2.6.32-21 with USB. Not only with Printer USB. I will try to reproduce and fix this issue. Thanks for your support!
