Have you checked the stuff with the Kernel module: ---------- 1. Remove "usblp" kernel module
lsmod | grep usblp sudo rmmod usblp If the module was still there, remove your "hp:..."-based print queue and re-plug the printer again. Does it stop creating the new queue now? Does the module stay unloaded? Or does it get loaded again? ---------- After making sure that the kernel module is unloaded and does not reappear when reconnecting the printer, please run again the commands which you have run. Does the "usb" backend discover your printer now? -- after upgrade, CUPS refuses to use existing PSC-750 'usb' config and creates a new PSC-750-2 'hp' config https://bugs.launchpad.net/bugs/422930 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
