What's more annoying than having the non-hp cartridges blocked is that you can't print anything, even when there is a genuine HP cartridge installed. I need to print something in black and I can't do that because it doesn't print when there are empty HP cartridges installed and it won't recognise non-HP cartridges. This is a complete joke.

There is no option to Downgrade the Firmware of the printer.
Refer to this document: https://support.hp.com/in-en/product/hp-officejet-pro-8720-all-in-one-printer-series/7902032/model/7... for Updating or Upgrading Printer Firmware.
Keep me posted, how it goes!
