Printing apparatus, method of correcting in printing apparatus, and storage medium storing program thereof

Abstract

A printing apparatus includes a sensor for detecting temperature of a printhead and outputting the detected temperature as a voltage, and a controller for detecting the voltage, which has been output by the sensor, via a cable and controlling driving of the printhead. The apparatus further includes a switch settable to two states, one in which current is supplied to the sensor and one in which current is not supplied to the sensor; and a correction unit that subtracts a first voltage detected by the controller in a case where the state in which current is not supplied to the sensor has been set by the switch from a second voltage detected by the controller in a case where the state in which current is supplied to the sensor has been set by the switch, thereby obtaining a correction voltage corrected for a crosstalk component produced in the cable.
