I think HP already tried to block 3rd party ink and was sued? Either way, the DRM has been used to 1.) void your warranty as soon as a non-HP cartridge is installed and 2.) activate a kill bit in the cartridge DRM so it can’t be refilled and sold by 3rd party services. Any printer that reads a flagged cart will reject it.
