Abstract
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 flow velocity peak timing of a main jet of the pulsed liquid jet, and a control unit that sets a rising portion of the drive voltage waveform according to the index value so as to control changing of the drive voltage waveform.
