Well-Behaved Raster

PCL raster images are processed most efficiently when the height and width of the image are specified before the Raster Start command begins an image data transfer. Furthermore, the entire image should be transferred before using the End Raster command to end the image. If the image is broken into pieces, certain print artifacts such as lines or squares can appear in the image. These can occur when “nearest neighbor operations” are applied to pixels that appear to be at the edge of an image, but are really inside an image that has been artificially broken up into smaller images.
