The appearance of images printed by draft printing or the like is improved. Provided are, for example, a print head having a first dot formation section and a second dot formation section that are provided at positions that are offset from one another in a predetermined direction and that respectively form dots of different colors as said dots; and a controller for printing said image with the print head in a first resolution and in a second resolution that is lower than the first resolution based on data of pixels constituting said image to be printed, wherein, when the image is to be printed in the second resolution, the controller causes the first dot formation section and the second dot formation section to form the respective dots based on data of the same pixel in each printing operation.
