Ubuntu Version: 24.04.3 with GNOME
Printing and scanning on a network connected (wire connection) HP laser jet MFP M234dw worked straight away after a fresh install of Ubuntu 24.04.3 last week – very pleased.
But today no printing or scanning would work. Struggled for an hour. Even failed to work with a direct USB connection.
The simple fix was turning the router off and then back on again. This was despite the router continuing to otherwise work normally.
Just putting this here in case it works for someone.
Really enjoying 24.04.3 Previously used 20.04. Been using Ubuntu for over 10 years.
