Abstract
Image quality is improved by correcting printing position deviation arising between forward and reverse passes in the main scanning direction during bidirectional printing. An adjustment value is prepared with respect to at least one type of specific target dots other than those dots having the highest density out of the plural types of dots. Printing positions during forward and reverse main scanning passes are adjusted with the adjustment value to reduce printing positional deviation between forward and reverse main scanning passes.
