A liquid ejection control apparatus, which controls a drive voltage waveform applied to a piezoelectric element so as to control ejection of a pulsed liquid jet, includes a first operation unit that receives input of an index value for setting a position of an inflection point in a rising portion of the drive voltage waveform, and a control unit that sets the position of the inflection point in the rising portion of the drive voltage waveform according to the index value so as to control changing of the drive voltage waveform.
