I wish that were true for my Brother printer. I bought a basic but decent black and white laser printer of theirs several years ago, and it worked great for maybe 3 years, but then it started refusing to accept print jobs from all inputs (wifi, ethernet, USB, doesn’t matter, neither does the device sending the print job) and factory resets do nothing to help it. So now, it sits in a closet while the Canon inkjet with janky print heads that it replaced is doing print duty.
Apparently this can be fixed be reflashing its firmware but from what I can gather this requires some obscure utility that’s not generally available.
