Provided is a printing apparatus which includes a thermal head having a plurality of heat generation elements whose temperatures are controlled by applying a voltage and performing printing on a printing medium and a head drive circuit being supplied periodically with a control signal and print data to control application of a voltage to each of the plurality of heat generation elements. One period of the control signal includes first and second voltage application control periods which are separated from each other. The first voltage application control period is a period in which the printing is performed by controlling the application of a voltage, and the second voltage application control period is a period in which the printing is not performed and a temperature of the thermal head is adjusted by controlling the application of a voltage.
