Zusammenfassung:	A raster output scanner data controller reads pixels of an image from an image memory and outputs serially pixel data streams to a raster output scanner. The data controller includes an image memory storing a plurality of pixel data blocks in a scan line order, an image memory controller coupled to the image memory, a plurality of first-in, first-out memories coupled to the image memory controller for storing pixel data blocks corresponding to a plurality of beams, and an image controller coupled to the plurality of first-in, first-out memories. The pixel data blocks are transferred from the image memory to the plurality of first-in, first-out memories. The image controller reads the pixel data blocks from the plurality of first-in, first-out memories, converts the pixel data blocks read from the plurality of first-in, first-out memories into a plurality of pixel data streams and outputs the plurality of pixel data streams to the raster output scanner.
