Can it be that you have earlier installed HPLIP directly from the upstream source? The system update could have overwritten parts of that installation and now your HPLIP does not work any more.
A safer way to have an always up-to-date HPLIP is using its Snap version. Go to https://snapcraft.io/hplip-printer-app Install the Snap, set up your printer in its web interface, and CUPS will see a network printer, as the Snap emulates a network printer. Print to this network printer. In this Snap HPLIP is completely encapsulated and cannot be overwritten by any other installation. It gets also auto-updated by the Snap Store, so you will have an always up-to-date HPLIP. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1960601 Title: Ubuntu 20.04 stopped detecting HP LaserJet P2055dn after this morning's update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1960601/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
