Abstract
A drive system for driving the transducers of an ink jet print head. A controller determines transducer activation periods during which one or more selected transducers are to be activated. During each transducer activation period a voltage source is activated. A drive circuit receives serial print data from the controller and couples the selected transducers to the voltage source. The voltage source can be provided with a waveshape circuit to produce a desired excitation waveshape.
