摘要：
In an ink-jet printing apparatus which includes a plurality of printing heads each having an array of ink discharging elements, preliminary discharge of driving the elements of at least one printing head is performed a predetermined number of times as a unit in performing preliminary discharge of discharging ink irrelevant to printing. The printing head for which the preliminary discharge is to be performed is switched in a predetermined cycle. In performing the preliminary discharge and switching of the printing head are so controlled as to perform preliminary discharge a desired number of times for all the elements of the printing heads by repeating the cycle.
