Abstract
A digital printing apparatus accepts image data in the form of PDL files, and also instructions, external to each PDL file, about shifting images formed at the PDL file to precise positions on a print sheet. The PDL file is interpreted to yield a raw bitmap, and then compressed according to a compression algorithm. The external shift instructions are then included in the compressed data as blank-line instructions which add a number of blank lines equal to a number of scan lines the image is desired to be shifted. The shifting is useful for accommodating bindings in the finished printed documents.
