I do think it's pretty ridiculous that rossman of all people would not verify any of this before making a video about it. At least reach out to the company and ask them for a comment.

Thanks for added context!

I bought a 15 year old second-hand Brother laser printer - works like a charm, operates under both Windows and Linux, still has all the spare parts you can think of readily available, and you can just load any toner into the official cartridge to use it again, and again, and again.

Love it. Simple, dirt cheap, just works and does it well.
