Abstract:
The invention is concerning a head driving device that drives a recording head including a plurality of nozzles and a plurality of pressure generating elements corresponding to the respective nozzles. The head driving device comprises: a plurality of drive waveform generating units corresponding to the respective pressure generating elements, wherein the drive waveform generating units drive the respective pressure generating elements on the basis of pieces of drive waveform information that are set for the respective nozzles so as to approximately equalize ejection characteristics of droplets ejected from the nozzles.
