Abstract
The recording technique of the present invention is applied to a printer that has a print head, which causes a partial area of main scan to have a lower positional accuracy of dot creation, and carries out bi-directional printing, which causes the print head to create dots on a printing medium in both forward and backward passes of the main scan. The recording technique records dots in such a manner that forward pass dots created in the forward pass of the main scan and backward pass dots created in the backward pass of the main scan are present at substantially equal rates in at least specific areas close to both ends of the main scan. This arrangement of the present invention desirably improves the printing quality in the case of bi-directional printing.
