A printer of the dot matrix type for printing, single, double and triple sized characters. Normal sized characters are printed in the conventional fashion. Double and triple sized characters are printed through a segmented technique in which segments of the double and triple sized characters are stored within readable memories (ROMS). For double sized characters which occupy two adjacent character lines, the segmented patterns for the upper portions of the characters are printed along the first normal sized character line. The lower half of the double sized characters is printed on the next adjacent character line by selection of the appropriate segmented patterns. Triple sized characters are printed in a similar manner, utilizing three lines of conventional sized characters. The same technique may be employed to create other graphic patterns of 1 to N lines, where N is a real integer equal to or greater than 2. The technique permits the utilization of either unidirectional or bidirectional printers.
