An ink supply device for inking the types of a hand labeler device, usually including at least two inking rollers which are rotatable over the type surfaces of a printing head; these ink rollers are removably held in an ink roller assembly which is, in turn, removably held in a movable holder; guide grooves in the side walls of the hand labeler frame guide the ink rollers over the type surfaces; roller cartridge frames are attached removably to the ink roller assembly for holding the ink rollers; retaining projections formed on at least one of the cartridge frames retain it in the holder and the projections act as knobs for attachment and removal of the corresponding cartridge frame, thus facilitating replacement of the ink rollers. In a second embodiment, the ink roller assembly includes one or more roller holders for rotatably holding the ink rollers; a pair of elastically biased knobs are removably attached to the roller holder, and each is formed with a retaining pin; a support member of the assembly is attached to the link mechanism of the hand labeler for removably holding the ink roller assembly; the support member includes retaining holes for receiving the retaining pins; actuating members which elastically bias the support member.
