Abstract: A raster type printer that utilizes a display list and crossing queues to represent the primitive objects of a page image formed of dots on an array of pixels logically organized in a sequence of adjacent swaths each swath having a first boundary that is adjacent a prior in sequence swath, if any, and a second boundary that is adjacent a next in sequence swath, if any, wherein the display list contains for each swath a swath data list that includes object records for each primitive object included in the swath, wherein an object record for a primitive object is comprised of (1) an encoded description of the primitive object if the primitive object does not cross the first boundary of the swath, or (2) a crossing queue flag if the primitive object crosses the first boundary of the swath, and wherein the records in each swath data list correspond to a predetermined sequence of primitive objects on a page image.
