I just printed 200 pages last night on an HL- 5470DW with a cartridge that claimed to have run out a week ago. (I should probably print out the tricky “override” button sequence in case it disappears from online.) The print quality was starting to get a little rough, so I selected “improve toner fixing” in the advanced print settings; this slowed the printing a bit, but the print looked great. I don’t know which printers have this option in their drivers, I think the old HL-1440 in my office does not.
I can’t see Brother doing this, they are a pretty pro-customer company. Canon on the other hand is terrible in this regard. A couple of years ago I bought a Canon Pixma inkjet printer while living in Norway, the cartridge for the model went on sale at Best Buy in the US so my wife brought one over for me. It wouldn’t work, and after wasting an enormous amount of time on troubleshooting (including finding and trying hidden menu commands) the company finally admitted to me that they region-locked cartridges in firmware to prevent customers finding deals in other countries.
