Perform root-level uninstallation to remove all printer-related software.

• In Windows, search for and open Programs and Features.

• Open up the run command with the "Windows Key + R" key combo.
• Type printui.exe /s and click OK.
• Click on the Drivers tab.
• Look for an HP Printer driver. If you see it click on it and click Remove at the bottom.
• Select OK.
