Some are good, some are bad, buyer beware.

No direct experience, but I recently read[1] Brother HL-L3220CW counts printed pages, and refuses to print after a set number of pages, even if there's still toner in the cartridge. Some models have a way to reset the page count but this one apparently does not.

(I also use a Brother B/W laser printer, got it second hand for almost nothing, works fine)
