When bidirectional multi-pass printing is carried out by use of a printing head having an inclination, even if a bidirectional printing is somewhat displaced, an inclination of a printing position is corrected in a state where “band unevenness” is suppressed as much as possible. In order to realize the correction described above, a division number B for dividing a plurality of printing elements into a plurality of blocks, and a timing at which each of the blocks is driven, are set on the bases of inclination information on the printing head and the number of multi-passes. Thus, even if the bidirectional printing is displaced, printing widths are equally increased or reduced in the respective regions. Consequently, it is made possible to avoid the “band unevenness” which is caused by differences in the printing width among the regions.
