PROBLEM TO BE SOLVED: To suppress a shift of the recording position of a dot in a main scanning direction when using plural kinds of driving signals in one page. SOLUTION: One of n kinds (n is an integer greater than or equal to 2) of common driving signals is selectively generated by each main scanning. By shaping the selected common driving signal in accordance with a printing signal by each pixel, a driving signal to be applied to each ejection driving element is generated. In all of the combinations of plural kinds of the common driving signals which are possibly used in the main scanning of the outward passage and plural kinds of the common driving signals which are possibly used in the main scanning of the inward passage, a recording position in the main scanning direction is adjusted by using a position shift adjusting value prepared beforehand for reducing the shift of the recording position in the main scanning direction in terms of each combination which is possibly used in one page of a printing medium. |
