Abstract
There is provided a printing apparatus including: a head having a discharge surface in which a nozzle configured to discharge a liquid droplet in a first direction is opened; a light-emitter configured to emit light; a light-receiver configured to receive the light; a gradient adding member configured to add a gradient to a light intensity of an optical path of the light in each of second and third directions, the second and third directions intersecting the first direction, the second and third directions intersecting with each other; and a controller. The optical path intersects a flying area in which the liquid droplet from the nozzle flies at a position between the gradient adding member and the light-receiver. The controller is configured to detect a deviation of a flying direction of the liquid droplet based on an amount of the light received by the light-receiver.
