HP has done the ink cartridge shenanigans for more than 30 years now. They just recently found a new trick. Apart from that nothing has really changed.
I am not aware Brother ever did similar things to basically trick or cheat their customers. Most other vendors are somewhere in between. AFAIK none are as bad as HP.
My dad is running his Brother HL-1212W printer on the open source Linux driver, works perfectly fine, and I was actually surprised about the high quality of his prints for such a cheap printer.
AFAIK Brother is among the best regarding opensource drivers too.
All this printer talk almost makes me want to buy a new printer. My current printer is a 14 year old Samsung color laser, and the print quality is not that stellar anymore. ;) The Samsung open source driver kind of suck for this printer. There isn’t even a driver for this specific model CLP-325W, so I have to choose another Samsung printer that is (mostly) compatible.
The Brother printer was completely plug and play. The system recognized the printer, and installed the correct open source driver, no hassle at all.
