PROBLEM TO BE SOLVED: To provide a technique for suppressing deterioration of an image quality caused by printing a print image by scanning a common area on a print medium several times. SOLUTION: The printing method of the present invention includes a step of generating dot data representing a status of dot formation on each of print pixels by performing a halftone process. The print image is formed by mutually combining dots formed on print pixels belonging to each of a plurality of pixel groups having an assumed physical difference. The halftone process is characterized by being configured so as to provide all of dot patterns formed on the print pixels belonging to each of the plurality of pixel groups, with specified characteristics, and also so as to equalize the numbers of the dots formed on the print pixels belonging to each of the plurality of pixel groups, for each of gradation sequence.
