Apparatus and method of generating waveform for driving ink jet print head

摘要

An apparatus and a method of generating waveforms for driving an ink-jet print head. Waveform data for the overall head-driving waveforms per given unit are written in waveform buffers and then sequentially retrieved at a given timing for analog conversion to obtain an analog head-driving waveform signal. Various head-driving waveforms are thus programmably generated.
