HP ink cartridge DRM bypass demonstrated using physical man-in-the-middle-attack

Super-thin PCB stops the cartridge from counting how many pages you've printed.

YouTube creator Jay Summet shared a video (via Hackaday) showing this particular attack that lets users bypass HP’s user-unfriendly DRM practices. The chip hack is the latest attempt that third-party ink makers have made to assuage the negative experience consumers have with printers — particularly, HP-branded ones. But as it takes time for cases like this to go through the legal system, users have to resort to creative solutions to keep their printers usable without having to pay through the nose for ink.
