Abstract
A printing apparatus includes a control unit configured to perform control so as to apply a first driving voltage to a heat generation element to discharge ink from an orifice and then apply a second driving voltage to the heat generation element so as not to cause bubbling or discharging of ink. In this case, the control unit performs control to apply the second driving voltage before detection of a feature point on the waveform of a signal representing temperatures in a temperature drop process detected by the temperature detection element after application of the first driving voltage and along with the application of the first driving voltage based on a temperature detected by a temperature detection element.
