I have discovered the same problem today. Something in the kernel or UDEV has changed which made HPLIP generally not seeing HP printers on USB anymore. I have observed it for 3 printers: HP PhotoSmart A710, HP LaserJet 3390, HP LaserJet 1020. These are very different models, so probably all HP printers are affected.
This is a severe problem, so I raise its priority to "Critical". I also add tasks for UDEV and the kernel. ** Changed in: hplip (Ubuntu) Importance: Undecided => Critical ** Changed in: hplip (Ubuntu) Status: New => Triaged ** Also affects: linux (Ubuntu) Importance: Undecided Status: New ** Changed in: linux (Ubuntu) Importance: Undecided => Critical Assignee: (unassigned) => Ubuntu Kernel USB Team (ubuntu-kernel-usb) Status: New => Triaged Target: None => hardy-alpha-3 ** Changed in: hplip (Ubuntu) Target: None => hardy-alpha-3 ** Also affects: udev (Ubuntu) Importance: Undecided Status: New ** Changed in: udev (Ubuntu) Importance: Undecided => Critical Status: New => Triaged Target: None => hardy-alpha-3 ** Also affects: libusb (Ubuntu) Importance: Undecided Status: New ** Changed in: libusb (Ubuntu) Importance: Undecided => Critical Status: New => Triaged Target: None => hardy-alpha-3 -- [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 the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
