Zusammenfassung:	There is disclosed a printing, feeding and severing method and apparatus for carrying out the method. The apparatus includes a print head assembly and a platen assembly movable relatively toward and away from each other into and out of printing cooperation, mechanism for feeding a web of record members to between the print head assembly and the platen assembly, record severing means disposed downstream of the print head assembly and the platen assembly, and a modular support assembly of a print head of the print head assembly. In one embodiment, a first gear is connected to the movable platen assembly meshing with a second gear which drives a cam. The drive connection between the cam and the ink roll includes separate carriages carrying the ink roll. Movement of the platen assembly causes the ink roll to move sequentially between a source of ink and the print head. In another embodiment, a driven cam, mounted for movement on the movable platen assembly operates a bell crank, rods, and arms, which arms carry an ink roll for inking the print head.
