A page to be printed is organized into a plurality of strips. To rendered the page using a tandem printer, each strip is rendered a plurality of times, once for each print engine of the tandem printer. Each time the selected strip is rendered for a different one of the print engines, the rendered image data for that print engine is stored into a separate memory area, such as a buffer, associated with that print engine Once a selected strip is rendered and the rendered image data stored into the associated memory areas, the rendered image data is used by the appropriate print engines to form image portions on a receiving sheet corresponding to the rendered image data. At the same time, a next strip is selected and repeatedly rendered for each of the print engines.
