My kiddo bought a new printer in 2015 because he had to print something for high school and the toner cartridge was empty. It was cheaper to buy a whole replacement brother with the starter cartridge than to just get a cartridge (and it was delivered for free within the a couple of hours!). I still have it, still use it once in a while, and it's still on that same starter cartridge and maybe the same ream of paper. Two more kids have finished high school using it...hardly at all.
In the past year I can remember two printer jobs, each a single page.
