ABSTRACT:
A printing method in which a pixel is resolved into a matrix and the gradation of a picture is variably set by dots printed in each pixel. The method includes a line setting step of setting a print density for lines corresponding to the main scanning direction along which dots are arrayed, and a dot-based printing step of printing dot-by-dot along the main scanning direction based upon line-based print densities set by the line setting step. A picture printing device employing such printing method is also disclosed.
