I have the same problem as lots of other. My HP 4657 was working fine but suddenly stopped after upgrading to 20.04.1 LTS when it failed to connect to the printer (tried both wireless and usb).
I downloaded hp-lip 3.20.6.run (again) and reinstalled, uninstalling the old install during the process but it keeps coming up with the same error as before - Canberra-gtk is missing. In HP-setup it finds the printer ok but refuses to load and keeps in a loop of 'add printer'. HP are no use and say it is not their software and is third-party software!
And yes, I typed in systemctl list-units "ippusbxd* | grep service
in terminal and nothing came back.
sudo apt install libcanberra-gtk-module
