A single dot on a recording medium is formed by dots of a plurality of ink droplets ejected from different orifices 201 of a head 107. For example, four dots are formed overlapping one on the other to form a single dot. In order to suppress unevenness in ink density of a recording image due to undesirably shifted impact positions of these dots, impact positions of the dots for the single dots are shifted to the right and left on purpose by ¼-dot-worth of distance for each, that is, ½-dot-worth of distance in total. This printing method has a good effect on controlling noise element, which has a high special frequency and causes uneven ink density.
