Abstract
A printing apparatus includes a printhead with a plurality of print elements for generating energy used for printing an image on a print medium, a first temperature detection element and a second temperature detection element at positions different in a direction of a print element array in which the plurality of print elements are arrayed. The apparatus corrects a signal concerning a head temperature based on an output from the first temperature detection element, and corrects, based on the corrected signal concerning the head temperature, a signal concerning a head temperature output from the second temperature detection element.
