Half a year ago I was fed up with windows and decided to install Xubuntu. I first tried a live system of Focal Fossa, but my printer, an HP Officejet Pro X451dw wouldn't work. I found out, that it does with Bionic Beaver, installed it and worked happily with it since. Yesterday I decided to upgrade to Focal Fossa, because the support for Bionic Beaver will run out soon. But unfortunately, the problem reoccurred. The printing utility detects the printer, but I can't print. I get a notification, that the printer is not connected, which is definitely wrong. I have disconnected the USB cable and reconnected it to varying USB slots, but that didn't change anything. I removed the printer from the printing utility and reinstalled it, without success. I ran troubelshooting and got the following protocol:

Does anybody know a solution to my problem? May I use Focal Fossa with an older version of the printing utility? How dangerous would it be to reinstall Bionic Beaver and continue using it, after the support runs out?
cups
? Have you installed hplip, which is also an Ubuntu package calledhplip
? (Maybe the GUIhplip-gui
package would also help?)sudo apt update; sudo apt install hplip hplip-gui
. You've also installedcups
