Wolfgang Glas, the security update in CUPS is most probably not the culprit, as the hardware access is not done via CUPS but through the HPLIP CUPS backend and the backend communicates directly with the kernel.
Possible causes for the bug: 1. A kernel update broke the USB stack. Did you get asked for rebooting the system after one of your last updates? Did you actually reboot? 2. Problem with AppArmor. In this case proceed as described under "AppArmor Protection of the printing system" on https://wiki.ubuntu.com/DebuggingPrintingProblems andschuster, most of HP's printers still work on Lucid, otherwise we had a lot more bug reports. I have also many HP printers and I did not see any problems with them. But in general this should get fixed for the LTS. -- after the last updates printer stopped working https://bugs.launchpad.net/bugs/595650 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
