A printing apparatus includes a liquid discharge device, a carriage, and a controller. The liquid discharge device includes a first nozzle row to discharge a first liquid to form an image and a second nozzle row to discharge a second liquid of a type different from the first liquid. The carriage is mounted with the liquid discharge device and reciprocally movable in a main scanning direction. The controller is configured to control the liquid discharge device to discharge the second liquid onto a region of a medium including another region onto which the first liquid is discharged. The controller includes a control unit to control the liquid discharge device to discharge the second liquid from the second nozzle row in both of forward movement and backward movement of the carriage and discharge the first liquid from the first nozzle row in one of the forward movement and the backward movement.
