ABSTRACT:
High speed printing apparatus for printing on light sensitive material includes a circuit adapted to receive at least one input signal which provides a control signal in accordance with a received input signal. A laser scans the material and provides pulses of light which strike the material in accordance with the control signal so as to expose the light sensitive material at the point of striking. The exposed film is developed so as to provide a printed copy in accordance with the received input signal.
