What is Brother doing now? I haven’t heard that with Brother printers and I had one for years.
Some of their software started to get pushy, and their toner cartridges started to ‘be empty’ too early - with some new printers also having ‘trial’ toners with almost no toner in them. Mellow compared to the alternatives.
Coincidentally, many HP and Canon laser printers use slight variations of the same toner cartridges such that third parties can support both printers with the same cartridges:

I am curious if this is also true for the inkjet printers, but finding out would probably involve buying every cartridge and comparing. I cannot justify that expense to sate my curiosity.
