Hi, I'm Bernard, a fellow Windows user. I'm happy to help!
I understand the issue you have. There is nothing to worry about. I am here to assist. This issue occurs when the HP driver is still installed on the Windows 10 PC and is having a conflict. To sort out the issue, kindly follow the steps below:
Remove HP Printer from the PC:
Go to Settings > Devices > Printers & scanners
Click the HP Printer, then select Remove.
Or
Press the Windows key + R, then type in:
printui /s /t2
Then hit OK
Click the HP Printer > click Remove.
Once done, try to add the printer again: Go to Settings > Devices > Printers & scanners > Click Add a printer or scanner
If the issue persists, try to reinstall the HP Smart App, then check it again.
