You're not paying for ink cartridges silly, you're paying for how much you print!
It all makes sense: if you stop paying for the service, you stop receiving the service, duh!
It's not illegal so it's crazy that people think they're this evil corporation!
The last two times I needed my printer were a job interview in 2018 where the interviewer was adamant that I deliver my resume printed, signed, and through the mail and another time in 2021 where a doctor's office needed me to print a parking pass for some reason. Both instances were dealing with inexplicable weirdos.
That's what libraries are for imho. Why get a printer when you can use theirs for 10¢/page?
