I had similar issue wit HP DJ 845C - very old, but good printer. It is USB printer.
Printer didn't worked, hp toolbox show communication error 5012. After usb cable printer was working, printer dwo documents and again stopped (with the same error in hp toolbox). Cups interface (localhost:631) and KDE frontend simply shows, that document is "processed". I removed AppArmor, which caused problem with other printer - 710C (parraler port, not usb) , I will see if it helps. 710C is not supported by HPLIP, but removing apparmor (or simply removing apparmor rules for cups) helped. This was long time ago and I can't test apparmor now - maybe in 3 or 4 weeks. -- [Hardy]HP printer is not detected properly by HPLIP https://bugs.launchpad.net/bugs/181242 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
