If your HP printer won't print or scan, and you see a warning message like one of those listed below starting on or after October 22, 2020, you may need to replace your HP printer drivers to resume using your printer.

If your printer is AirPrint-enabled, you can remove it in System Preferences > Printers & Scanners, and then connect to and add the printer using AirPrint.
