Discharge waveform generating device, method of generating discharge waveform, and non-transitory recording medium storing program

Abstract

A discharge waveform generating device includes a timing reference generation circuit, a timing adjustment circuit, a waveform pattern generation circuit, and a timing correction circuit. The timing reference generation circuit generates a discharge timing for generating, from image data, a discharge waveform of ink to print the image data, based on a line synchronization signal for synchronizing discharge operations of discharge nozzles to discharge ink. The timing adjustment circuit sets an adjustment value of the discharge timing. The waveform pattern generation circuit generates the waveform from the image data, based on outputs of the timing reference generation circuit and the timing adjustment circuit. The timing correction circuit causes the waveform pattern generation circuit to start generation of the waveform in a condition in which the waveform pattern generation circuit has not finished the generation of the waveform when the timing reference generation circuit receives the line synchronization signal.
