Abstract

A recent inkjet printing apparatus includes a large-capacitance capacitor to stabilize a heater power supply. The presence of this capacitor requires a long time to drop the heater voltage at the time of power shutdown or the like. For this reason, an unwanted heater current may flow during the drop. To solve this problem, in this embodiment, a high voltage logic circuit is provided near a printing element, and a terminal is provided so that a signal can directly be input to this circuit. Heater driving control is performed via the terminal. This makes it possible to reliably control the heater regardless of the logic power supply state even if the logic voltage abruptly drops at the time of power shutdown or the like.
