PROBLEM TO BE SOLVED: To solve a problem in 600dpi printing having a fading or obscure edge and a method of printing a double or multiple pixel with a clear-cut edge on both sides, and further a method of dual-route and bidirectional printing that forms an image of high resolution of a double or multiple pixel with a clear-cut edge in high frequency. SOLUTION: The method of printing a pixel image on a paper sheet or web for which a printer has a printer head that reiterates its action across the paper sheet or web along the first route of the first direction and an opposite second route of the second direction. Such a pixel image includes the first and second pixels locating at a preceeding or an upstream portion of the image being considered at the first and second directions and is composed of a plurality of pixels neighboring their locations as are seen in the first and second directions and such a printer head forms the first and second pixels only when moving toward the first and second directions, respectively.
