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

A discharge waveform generating device comprising:

• timing reference generation means for generating a discharge timing as a timing reference for generating, from image data, a discharge waveform of ink to print the image data, based on a line synchronization signal as a reference signal for synchronizing discharge operations of a plurality of discharge nozzles to discharge ink;
• timing adjustment means for setting an adjustment value of the discharge timing, based on the discharge timing generated by the timing reference generation means;
• waveform pattern generation means for generating the discharge waveform from the image data, based on outputs of the timing reference generation means and the timing adjustment means;
• and
• timing correction means for causing the waveform pattern generation means to start generation of the discharge waveform in a condition in which the waveform pattern generation means has not finished generation of a currently generated discharge waveform when the timing reference generation means receives the line synchronization signal.

A method of generating a discharge waveform, the method comprising:

• generating a discharge timing as a timing reference for generating, from image data, a discharge waveform of ink to print the image data, based on a line synchronization signal as a reference signal for synchronizing discharge operations of a plurality of discharge nozzles to discharge ink;
