Abstract
A drive circuit for a drop-on-demand ink jet printer utilizes the inherent capacitance of the driver electromechanical transducer to store at least a portion of the voltage required for droplet ejection. The drive circuit includes circuitry for sensing and terminating, for example, rapid discharge of the electrical potential difference across the electromechanical transducer during jet firing.
