ABSTRACT:
An inkjet printer and inkjet print cartridge are each especially configured for inter-engaging with one another via a plurality of keying features of the cartridge and keying structures of the printer such that loading of a foreign print cartridge into the printer is either not possible or results in the printer being inoperative. Thus, only print cartridges particularly configured and intended to be used in the printer will fit into the printer and enable its operation.
