My Brother printer does not connect to my Linux computer over Ethernet on the same network no matter what I do. I have to physically connect PC to the printer for it to work. It also doesn't wirelessly work with it. I can only wirelessly talk to it through my phone using their app.
I hate printers. The moment someone offers a high quality, non-scummy, easy to use in every basic scenario printer compatible with Linux I will buy it and never stop buying it until something changes in those categories. Laser, inkjet, whatever. My use cases are hex maps and legal documents. If I could get a printer that made TCG quality cards in my house I'd buy that as well for a substantial price but that's because my childhood was saturated with card games and their animated shows. I digress.
Please make a good printer. Brother was supposed to be that but I've not had any success with their stuff for the past 6 or 7 years, even on windows.
