Abstract
A printing apparatus that includes printing element substrates which are provided with printing elements that discharge ink. A plurality of temperature sensors, each of which is provided with one of the printing element substrates, measures a temperature of a corresponding printing element substrate. A selection unit selects any one of the temperature sensors, and a determination unit performs a determination operation to determine a state of the printing element substrate based on the temperature measured by the selected temperature sensor in a case when only the printing elements of a substrate that corresponds to the selected temperature sensor are driven. The determination unit performs the determination operation on a first substrate and then on a second non-adjacent substrate.
