After the recent Catalina OS 10.15.7 download my HP printer was axed. But thankfully with the help of DiZoe I got the printer back up via his great instructions.
Today I tried to scan and another Klingon message was received: "Scanner reported an error. The operation couldn't be completed. com.apple.imagecapture error704." My scanner is part of my HP F1480 Deskjet printer
Is there anyone out there from The Borg who has an idea how I can use my scanner again? Thanks in advance for your help.

Update: HP Printer Software 5.1 should now be becoming available through Software Update to fix this issue.

If you still have an issue, and listed as AirPrint printer, delete the existing printer in
> System Preferences> Printers & Scanners, and add it again, select AirPrint.
Connect an AirPrint printer to a Wi-Fi network - Apple Support.
