ABSTRACT:
A printing system prints an image on a printing surface of a printing medium with a print head array having multiple columns of print heads, such as electro-mechanical actuator impact or non-impact print heads, ink-jet print heads, or bubble jet print heads, having varying positions in a vertical dimension in the print head array for printing in a corresponding printable column area of the image. The printing medium is moved relative to the print head array in the vertical dimension to cause selected non-contiguous portions of a defined printable segment along a horizontal dimension to be printed in each printable column area by the print heads having varying positions in the vertical dimension. Further movement in the vertical dimension causes selected non-contiguous portions of multiple defined printable segments to be printed. By combining the movement in the vertical dimension with movements of the print head array relative to the printing medium in the horizontal dimension of not more than the widest distance between any two consecutive non-contiguous portions, all defined printable segments contained in the image are printed.
