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 Desktop Packages, which is subscribed to cups in Ubuntu. https://bugs.launchpad.net/bugs/1960601 Title: Ubuntu 20.04 stopped detecting HP LaserJet P2055dn after this morning's update Status in cups package in Ubuntu: New Bug description: I printed yesterday. I updated Ubuntu 20.04.3 this morning. The system now does not detect the HP LaserJet P2055dn to which it has been connected for years. The output of the command "apt-cache policy cups" is: cups: Installed: 2.3.1-9ubuntu1.1 Candidate: 2.3.1-9ubuntu1.1 Version table: *** 2.3.1-9ubuntu1.1 500 500 http://archive.ubuntu.com/ubuntu focal-updates/main amd64 Packages 500 http://archive.ubuntu.com/ubuntu focal-security/main amd64 Packages 100 /var/lib/dpkg/status 2.3.1-9ubuntu1 500 500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages What I expected to happen was to print a document. Then, for the system to recognize the printer when I tried to reinstall it. What happened instead was that printing failed. Settings > Printers > Additional Printer Settings vomited an error message saying that the printer may not be connected. The print job hung on "Processing" for 5-10 minutes before I terminated it. I deleted the printer on the system and the system would / could not detect the device. No obvious means exists to install a printer driver for a specified printer, which is an astonishing design failure for the platform. I have rebooted the system and the printer multiple times throughout this process. I also attempted to update the system but no updates are available. All the wiring and power is as before. The system recognizes any number of other USB devices connected to it, including scanners, etc., that are freshly powered on. Power cycling the HP printer has no effect on lsusb output.
