I’ve seen reviews saying that a firmware update stopped 3rd party ink/toner from working. Both myself and my mom have Brother printers that we love and have used for years. It’s disappointing and they’re great printers but I don’t want to pay a premium on toner/ink just because. But yeah, as @cerberus_cat said, refillable ink is good too if you need an ink jet printer but I don’t know why anyone would want ink over laser.
