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.

Abstract: A printing apparatus includes a guide unit provided with a guide surface configured to guide a medium by coming into contact with the medium on which printing has been performed, and a heating unit disposed to face the guide surface with a space therebetween. The heating unit includes a first opening portion that opens toward the guide surface on an upstream side in a transport direction, a second opening portion that opens toward the guide surface on a downstream side in the transport direction, a duct connecting the first opening portion and the second opening portion, and a first blowing unit disposed inside the duct. The printing apparatus switches a direction of airflow produced in a heating region in response to a switching of a blowing direction of the first blowing unit.

Abstract: A recording apparatus includes a recording head that ejects liquid onto a recording medium, a transporting device that transports the recording medium along a supporting surface of a supporting member, and a preheating device that preheats the recording medium to the upstream side of the recording head in a transporting direction of the recording medium. The preheating device includes a preheating unit that increases the amount of heat per unit time which is applied to the recording medium as the recording medium is moved toward the downstream side in the transporting direction. The supporting member includes the supporting surface and bending portions.
