A technique is described whereby a single printing unit integrates two distinct printing capabilities - dot matrix printing and fully formed character printing - into one operational unit. The single printing unit consists of housing 10, as shown in the figure, which contains printwheel actuating mechanism 11, wire matrix actuating mechanism 12 and inked ribbon mechanism 13. During the printing of fully formed characters, wire matrix actuating mechanism 12 is retracted away from the paper and ribbon enabling printwheel actuating mechanism 11 to be positioned so as to allow its printwheel 14 to rotate. The rotation of printwheel 14 will allow a character pedal 15 to be positioned to the top location for printing. Once positioned, wire matrix actuating mechanism 12 allows its wires to strike pedal 15.
