Abstract: A liquid droplet ejecting apparatus includes a transport unit configured to transport a medium in a transport direction, a support configured to support the medium transported by the transport unit, a liquid droplet ejecting portion configured to eject liquid droplets to the medium supported by the support, a carriage configured to reciprocate in a scanning direction intersecting the transport direction while holding the liquid droplet ejecting portion, and an air flow generator configured to create an air flow in an area over the support. The air flow generator limits creation of the air flow when the liquid droplet ejecting portion faces the medium in an ejection direction and allows the creation of the air flow when the liquid droplet ejecting portion does not face the medium in the ejection direction, due to movement of the carriage in the scanning direction.

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.
