Abstract

Provided is a technique capable of detecting the amount of a stack of discharged print media and increasing print speed. A printing apparatus includes a displacement member configured to be in contact with the discharged print media and be displaced according to the amount of the stack of the print media, and detects the stack amount based on the displacement of the displacement member. The apparatus performs a first or second detection operation based on the detected stack amount. In the first detection operation, after a specified number of print media are discharged with the displacement member positioned at the evacuation position where it does not come into contact with a print medium, the displacement member is brought into contact with the print media to detect the stack amount. In the second detection operation, the stack amount is detected with the displacement member in contact with the print media.
