ABSTRACT OF THE DISCLOSURE A multiple cross-hammer printer has a rotatable drum driven by a motor, a plurality of ridges formed on an outer peripheral surface of the drum and extending parallel to each other axially on the drum, a print head movable parallel to and axially on the drum in front thereof, the print head having a plurality of electromagnetically actuatable print hammers extending across a selected one of the ridges in confronting relation and spaced in parallel relation from each other in a direction of movement of the print head, and an ink ribbon movable with the print head and having a portion running obliquely across and infront of the print head, the ink ribbon having a plurality of parallel color strips extending longitudinally thereon and impregnated respectively with inks of different colors, the print hammers being disposed in confronting relation to the color strips, respectively. The print hammers are selectively actuatable to press the corresponding color strips on the ink ribbon selectively against the ridges, whereby multicolor printing can be effected on a recording medium positioned between the drum and the print head while the latter moves in one stroke.
