Definitely the Firewall…
Problem solved by resetting to factory defaults! :slight_smile:
“I” did not have to make any new rules; all I did was RESET to FACTORY DEFAULTS and the printer started working. I also rebooted the PC at Avast’s suggestion after resetting to factory defaults. It said some settings wouldn’t take place until I did.

Thanks for the help! Thanks to all of you! Now to my friends printer and see it works there too! ???
