Welcome to HP Support Forums. A really great platform for posting all your questions and finding solutions.
 

I have gone through your Post and I'll try my best to help

I suggest you start with a Printer Reset

(1) Turn the printer on, if it is not already on.
(2) Wait until the printer is idle and silent before you continue.
(3) With the printer turned on, disconnect the power cord from the rear of the printer.
(4) Unplug the power cord from the wall outlet.
(5) Wait at least 60 seconds.
(6) Plug the power cord back into the wall outlet.
 NOTE: HP recommends connecting the printer power cord directly to the wall outlet.
(7) Reconnect the power cord to the rear of the printer.
(8) Turn on the printer, if it does not automatically turn on.

The printer might go through a warm-up period. The printer lights might flash, and the carriage might move.
Wait until the warm-up period finishes and your printer is idle and silent before you proceed

 Then uninstall the printer driver from Root Level and download the Full Feature Software and the Firmware

1.) In Windows, search for and open Programs and features 
2.) Select your HP Printer 
3.) Select Uninstall 
4.) In Windows, search for and open Devices and printers 
5.) In the Devices and Printers windows look for your HP printer. If you see it listed right-click on it and choose ‘Delete’ or ‘Remove Device’ 
6.) Open up the run command with the “Windows key + R” key combo.
7.) Type printui.exe /s and click Ok. (Note: there is a space in between “printui.exe” and “/s”) 
8.) Click on the “Drivers” tab 
9.) Look for HP Printer driver. If you see it Click on it and click Remove at the bottom 
10.) Select Ok 
11.) Select Apply and Ok on the Print Server Properties windows 
12.) Close Devices and Printers
13.) Restart the computer and download the Full Feature Software and the Firmware from Here and follow the onscreen Instructions

Keep me posted how it goes and have a Great day 👍
