Welcome to the HP Support Community. I'd be happy to assist you with the "Printer Validation" error.
To better assist you -
1.) What's the operating system installed on the computer?
2.) Does the copy works?
3.) Have you tried printing from a different devices?
While you respond to that, let's try these steps -
1) Take out the cartridges.
2) Unplug the power cord from the printer & wall.
3) Wait for 30 seconds.
4) Plug the power cord back into the printer and wall, ensure the printer is plugged into the wall & not to a surge protector.
5) Insert the cartridges back into the printer.
Also, try updating the printer's firmware - HP Printers - Updating or Upgrading Printer Firmware
Hope this helps! Keep me posted.
