摘要:
An ink jet printing apparatus is provided that can realize a stable ejection volume with the minimum change in a voltage value supplied in a scanning. To realize this, when a detected temperature of a print head is included in a first range, a pulse width control is performed while a voltage being fixed to a first voltage. When a detected temperature is included in a second range, a pulse width control is performed while a voltage being fixed to a second voltage. In the pulse width control based on the two voltages, a temperature partially overlapped region is provided between the first range and the second range. By this, even when a print head has an increased temperature during a print scanning, an ejection volume can be controlled, in the print scanning, while minimizing the switching of a driving voltage.
