Abstract:
A printing apparatus (droplet discharge apparatus) includes a discharge portion that has a nozzle discharging ink to a medium and a control device that allows the discharge portion to discharge the ink depending on execution of a print job defining a mode for discharging the ink to the medium. Before the print job is executed, the control device calculates a discharge amount fluctuation which is a fluctuation in a discharge amount of liquid per unit time by the discharge portion based on the print job and determines whether or not maintenance for recovering ink discharge performance of the discharge portion is required at the time of executing the print job based on the discharge amount fluctuation.
