Abstract
A method and system for reproducing facimile images or other images in a dot matrix format wherein the normal printhead line resolution is not the same as the image line resolution. Two embodiments are disclosed. In the preferred embodiment, a commercially available printhead having two columns of dot forming elements is used. The printhead is slanted so as to change the effective spacing of the dot forming elements, and the dots making up the image are formed by the two columns alternately so as to increase the speed of operation. In the second embodiment disclosed, each of the scan lines of the image is comprised of dots formed by three dot forming elements. Each picture element is printed by two of the three dot forming elements and no two adjacent picture elements are printed by the same group of two.
