Printer problems
Since I upgraded to Monterey 12.1 my HP envy 6400 printer is not working properly. It is connected by wifi but when I hit print all the paper comes out of the printer blank. I can print fine from windows and my Ipad.
iMac Pro
That is not an airprint printer and drivers are required.
Try resetting the printing system

Last, readd the printer
