I had a Brother MFC a few years ago. It worked fine till I bought some off-brand toner. I kept getting whiny messages from it that had been filled with off-brand toner but it continued to work- till it didn't. It turned out the print driver was missing. There was no download available on the site for that model anymore so the machine was useless.
I'm comfortable enough with tech that I KNOW I would not have removed a print driver. I am convinced that some process on Brother's end erased it. Planet Money had done an interesting podcast on the subject of what printer companies were doing to force people to buy their overpriced toners and this type of sabotage was one tactic.
No more Brother printers for me. I now have an HP, B&W only so I'm not constantly buying toner in various colors. The local library is available for the few times I want color printing.
