摘要：
The present invention relates to an ink jet printing apparatus which sufficiently heats a head even in a low-temperature environment, which enables a proper image to be printed by stably ejecting ink, and which can be inexpensively and simply constructed. According to the present invention, if the detected temperature of a printhead is lower than a first heating threshold temperature, a heating mode in which the printhead can be heated is set before a printing operation. Further, when the heating mode is set and the detected temperature of the printhead is lower than a second heating threshold temperature, a heating unit heats the printhead. Consequently, even in a low-temperature environment, the heating operation keeps ink in a desired condition suitable for printing.
