Abstract
There are provided ink jet printing method and apparatus which assure that reciprocable printing can be realized at a high speed without any deterioration of a quality of printing. When an image is printed on a printing medium by using a multi-orifice head of which the ink ejecting direction relative to an opening surface is inclined in the return scanning direction, a scanning speed of the return scanning direction is delayed from the scanning speed in the reverse forward direction, an offset distance between a main dot and a satellite at the time of the return scanning is suppressed to be small, and in the case that printing is performed by reciprocable scanning, the satellite is received in the main dot not only during the forward scanning but also during the return scanning.
