Abstract
A method and apparatus prevents satellite induced banding caused in bi-directional printing in which a print head alternatively moves in a first printing direction and in a second printing direction opposite to the first printing direction. The ink jet printer includes a controller that performs at least one of (i) selectively removing pixels in the first printing direction in order to lighten an image, and (ii) selectively adding pixels in the second printing direction in order to darken the image.
