Abstract: PRINTING MECHANISM A printer of the wire type including 8 print wires disposed in a row and each actuatable by an electromagnet for printing individual characters defined by 8 dots high and 7 dots wide on a longitudinally movable ticket medium. The printing mechanism is also capable of printing fractions including numerators defined by the top 6 print wires and denominators defined by the bottom 6 wires together with a diagonally extending slash mark the printed dots of which lie within the 7 dot wide character areas and a 3 dots wide normally blank area between characters. The printing mechanism may be so controlled either by a hardware embodiment of control or a micro controller.
