BROTHER
Firmware policy
Brother says firmware updates do not block third-party ink or toner.
Stronger consumable freedom
Brother and HP currently publish materially different positions on third-party cartridge compatibility.
Brother explicitly says its firmware updates do not block third-party ink or toner cartridges. HP explicitly warns that printers using Dynamic Security may reject cartridges with non-HP chips, including cartridges that work today but may not work later.
Brother says firmware updates do not block third-party ink or toner.
HP says some printers use security chips or circuitry and that non-HP-chip cartridges may not work now or in the future.
This does not claim every Brother printer is better than every HP printer. It answers the consumable-freedom question.
