ABSTRACT:
A dynamically driven printer is provided for printing the output of a device having a memory register, the printer including print means operable directly from said memory register without an intervening temporary memory register in a manner corresponding to the operation of a segmented digital electronic display. The operating periods of the print means and memory register need not be synchronized. The print means may include a plurality of segment printing devices at each digit position, corresponding segment printing devices at each digit position being coupled together for simultaneous receipt of driving signals generated in response to the output of the main memory register. Each of the digit positions is sequentially actuated to effect printing.
