Two CMOS packages provide the four feed signals required for controlling forward/reverse drive of stepper motor for carriage drive and paper advance of Bowmar Model TP 3100 thermal printer. 0ut-puts of flip-flops are above 10V, enough to drive stepper motor directly. Each clock pulse to JK flip-flop advances carriage one step in direction commanded-R Bober. Stepper Drive Circuit Simplifies Printer Control、EDN Magazine , April 5,1976,ρ114.
