    Abstract: A method of rasterizing a print image plane for a multiple beam printer engine, which comprises the steps of receiving an image having a plurality of lines of print data for processing by the printer engine, and performing a print image plane rasterization. The print image plane rasterization includes (a) calculating a first line destination for a first line of print data; (b) moving the first line of print data to the first line destination; and (c) calculating a displaced line destination for a displaced line of print data, and continually moving the displaced line of print data to the displaced line destination until the displaced line of print data is moved to the first line and forms a loop. The process is repeated until each line of the plurality of lines has been moved to a line destination associated with each line of the image.
