Hi Sandytechy20,

Thank you for the info. I don't know if it worked because the link you provided to re-install won't open.

I am running Windows 10, 64 bit on a Sony VAIO laptop. Please advise a compatible link to re-install the printer & drivers. Let me know if you need any further info.


Many thanks!

Refer to this link: for Full Feature Software and Drivers.


If the issue persists, Use HP Print and Scan Doctor to check connectivity


Download a special version of HP Print and Scan Doctor.

  1. Download HP Print and Scan Doctor.

  2. Run HPPSdr.exe from the download location on your computer.

  3. Once HP Print and Scan Doctor opens, click Start, and then select your printer.

    • If your printer is not in the list, turn it off and on and then click Retry.

    • If there is a connection problem, follow the instructions in HP Print and Scan Doctor.

  4. If a screen prompts you to turn on printer updates, click Yes.

  5. If a screen prompts you to make your printer the default printer, click Yes.

  6. Try to print.

Keep me posted, how it goes!
