Abstract: An imprinter having a single driving device for controlling both the movement of the heated printing head and the intermittent advancing movement of the pigmented ribbon. The single driving device, which preferably comprises a reciprocal fluid pressure cylinder, causes the advancing and retracting movement of the printing head.

The zener diode responds to that firing signal by breaking down into a low resistance conduction path to thereby permit an electrical current sufficient to raise the second squib to incandescence to flow therethrough.
