There is provided, even in case plural sheet sizes or plural sheet orientations are mixed within a document, a system capable of obtaining an output result close to that of a document not containing such mixed sheet sizes or sheet orientations without causing sheet discharge in the course of printing operation or data overflow from the print area, also providing an enlarging/reducing function to a device lacking such function, and providing a visually agreeable output result, all realized without modification in the conventional printer driver. A host computer is provided with a spool file manager for calculating the relative position of the logic page to the physical page, and a despooler for processing the layout data, obtained by enlarging or reducing the logic page, to a data format matching the graphic engine.
