Abstract
A printing apparatus includes a position detection unit which includes an optical element, a light source and a light receiving element, radiates light from the light source toward the printing surface, causes diffused reflection light of reflection light which is reflected by the printing surface to be incident to the light receiving element through the optical element and outputs positional information relating to a position of the printing surface at which the light from the light source reflects, from the light receiving element, and a controller which causes movement of the carriage to stop when lifting up of the printing medium is detected on a basis of the positional information output from the light receiving element, in which a virtual plane which contains the optical element and the light receiving element is in a state of being inclined in relation to a normal line of the printing surface.
