Thank you for posting on the HP Support Community.

  • Did this happen after a recent window or software update?
  • Have you tried using an on-screen keyboard?

While you respond to that, let's try these steps: 

Follow the below steps to open On-screen keyboard.

  • Press Windows key and I at the same time,
  • In search box type On-screen keyboard  to the Find a setting box,
  • Select On-Screen keyboard and turn it On

Next, run Hard Reset: Follow steps from the link: https://hp.care/2GnkMa8.

BIOS default: 

  1. Turn off the computer and wait five seconds.
  2. Press the Power button to start the computer and repeatedly press the F10 key to enter the BIOS setup menu.
  3. On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.
  4. Press F10 to Save and Exit.
  5. Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?
  6. Follow the prompts to restart your computer.

If the issue persists run keyboard test from here

 

And for the printer: HP recommends that you use genuine HP ink or toner supplies. HP cannot guarantee the quality or reliability of non-HP or refilled cartridges.

Did you install a new cartridge? have you tried removing the ink cartridge and checked?

 

Try hard reset:

  • With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.
  • Remove USB cable, if present.
  • Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.
  • Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord (This is important) and then plug back the power cord to the printer.
  • Turn on the printer and wait till warm-up period finishes and the printer is idle.

Hope this helps! Keep me posted for further assistance.
