Data processing apparatus for condensed printing
View Patent ↗When multiple pages of a document are condensed and printed on a single sheet of printing media, an image data generator condenses the page image data by a prescribed reduction ratio. A sequence information overlayer overlays layout sequence information such as numerals or arrows, or borders or shading of different densities or colors, on the condensed image data. A recording device prints the condensed image data and overlaid sequence information on the single sheet of printing media. The reader of the condensed document recognizes the condensed page sequence from the overlaid sequence information, and can therefore always tell which page to read next. A print sample image of the single sheet preferably includes a sequence line graphically illustrating the page layout sequence.
