Abstract: Provided is a printing method for performing printing using a serial printer. In printing of a print image including a line image, the printing method includes a raster line forming step of forming each of raster lines configuring the image, by a plurality of pass operations. In the formation of each of the raster lines, when printing of a region corresponding to edge pixels of the line image by a first pass operation, which is one of the plurality of pass operations, is first printing, and printing of the region corresponding to the edge pixels by a second pass operation that is different from the first pass operation, of the plurality of pass operations, is second printing, a brightness of the printing by the second printing is higher than a brightness of the printing by the first printing.
