Abstract
In an ink jet printer provided with a printing head having an ink chamber, a piezoelectric element and a nozzle tip; the printer is further provided with a drive signal generating circuit for generating drive signals corresponding to image information, a temperature sensor for measuring the temperature of the printing head; and a heating signal generating circuit for generating a heating signal on the basis of the temperature of the printing head measured by the temperature sensor. The piezoelectric element vibrates in response to the heating signal and generates heat so that the ink in the ink chamber is heated.
