Abstract
An ink jet printer performs a control of a supply of electric power for each heating element based on a temperature dependency of a resistance value by monitoring its resistance value while ink is being discharged. Accordingly, the ink jet printer permits a damage of the heating element and a discharge inferior caused by a difference in characteristics in heating elements, ambient temperature, etc., to be suppressed. Additionally, as the temperature of the heating element is not detected directly, the ink jet printer permits high speed control of the electric value, thereby permitting high speed printing.
