I've spent hours chasing this problem. An HP tech signed into my laptop and after spending a couple of hours got it to print but the next time I started it up it wouldn't print.

I followed the instructions at the website in the email.

The error message says "There is no printer attached to the computer" but the computer shows me that it sees  the printer.

The problem is not in the printer, it is in the computer because my wife's windows machine prints from the printer.

This problem started when I switched from Windows 10 to 11 then back again.
