An object is to effect high quality printing of images such as photographs, designs, and the like, without using special paper. A printing apparatus includes a mechanism for supplying a recording medium that includes a recording medium surface, a mechanism for coating a surface modifier on a surface modification area of the recording medium surface, and a mechanism for drying the surface modifier coated on the surface modification area. The printing information to be printed on the recording medium surfaces includes image information. The mechanism for coating the surface modifier determines an area of the recording medium corresponding to the image information as the surface modification area. An image can be printed on the surface modification area with high quality. The present printing apparatus and method makes possible high quality printing with regular paper, without using expensive special paper, as before.
