An endless ribbon printer cartridge and cartridge mechanism apparatus is provided having a cartridge having a plastic housing with a pair of spaced rollers rotatably attached inside the housing. An endless inked ribbon is wrapped around the rollers with a feed from between the rollers over a predetermined path and back onto the ribbon wrapped on the rollers. A pair of elongated arms extend from the housing and the ribbon is fed from one arm to the other. The cartridge fits onto a cartridge holding mechanism mounted for horizontal movement with a rotatable cylindrical printing head. When the cartridge is mounted on the holder mechanism the arms extend on either side of the printing wheel to locate that portion of the ribbon passing between the arms between the rotatable printing head and a platen of a computer terminal printing mechanism. The cartridge may be easily inserted and removed by the operation of a latching mechanism.
