HP Firmware Update: Model overview and downgrade options

We recommend that all our customers switch off automatic printer updates in the operating system of their PCs. This way, they prevent manufacturers from being able to obstruct the functioning of their printers.

Whether or not a manufacturer is able to block use of third-party cartridges in your printer or not depends on its date of production, so not all printers are affected by this firmware update to the same extent. The following models have all been known to display error messages – if you know about other models, we can check them directly.
