A technique is described whereby a matrix print head incorporating twenty-seven wires (more or less) provides a dual function: (a) high density quality printing as required for Kanji characterization and graphics printing and (b) high-speed parallel printing for data processing (DP) application printing. Since Kanji printing normally requires a matrix print head consisting of a minimum of twenty-four wires, so as to produce quality characterization, the print head, as shown in Figs. 1 and 2, consists of twenty-seven wires to form the print head matrix. The additional wires provide a denser printing result, since the wires are closely packaged. To obtain the closely packed configuration, the wires are staggered, as shown in Fig. 1, so that, if all pins were operating together, the pins would form twenty-seven print planes.
