Abstract
A liquid discharge apparatus uses a drive signal including a micro-vibration waveform which causes the piezoelectric element to micro-vibrate such that an ink is not discharged from the nozzle in a case of being applied to the piezoelectric element as the drive signal and a drive waveform which deforms piezoelectric element such that the ink is discharged from the nozzle in a case of being applied to the piezoelectric element as the drive signal. The presentation unit selectably presents the indirect information from which the ink discharge status can be estimated such as the types of ink and the usage status of the ink or the like. The control unit changes the strength of the micro-vibration caused by the micro-vibration waveform based on the indirect information selected on the presentation unit.
