PROBLEM TO BE SOLVED: To stabilize printing of a regulation pattern for correcting print shift. SOLUTION: Scanning width of a carriage is kept constant at the time of printing a regulation pattern regardless of the sheet size or the type of regulation pattern. Approach running distance of the carriage at the time of printing a regulation pattern is set longer than that at the time of normal printing. Furthermore, scanning width at the time of printing a regulation pattern is set equal to that at the time of printing with a maximum print width.
