HP Printer Firmware Downgrade Download
This is where we usually host downgrade firmware files but HP filed a DMCA take down notice. We had to remove the files because HP doesn't want you to downgrade your firmware and get around HP's monopolistic and anti-competitive techniques of stopping aftermarket cartridges. Please call, email or tweet your local government official and tell them HP shouldn't be allowed to stop you from using aftermarket cartridges by forcing firmware updates on their customers.
