Many, if not most printers do not block 3rd party ink with firmware - it's the driver in windows that blocks that stuff. Many, if not most, block it with a driver in the OS.
Drivers can in essence have hotlists for additional filtering or be given access to communication with an ink chip by the firmware, but AFAIK downgrading a driver doesn't work because what has really happened is it updated the firmware.
A driver upgrade can also never be sufficient for blocking copying on a MFP printer, a standardized net print protocol as you mentioned or using open source drivers either on Linux or under WSL.
