Abstract
In a two-page printer system, there is included a first and second print engine placed on a path in which paper to be printed travels and displaced a distance, L, from one another along the path, the first print engine printing a first side of the paper and the second print engine printing a second side of the paper. The two-page printer system also includes an apparatus for coordinating the printing of the paper, the two-page printer further including a process controller for generating control signals. The apparatus comprises a first storage element for storing information to be printed. A processor element, operatively connected to the first storage element, formats the information to be printed in a form required by the printer, the information to be printed being fetched from first storage element. A second storage element, operatively connected to the processor element, stores the formatted information, the formatted information being transmitted to the first print engine in response to a first control signal and transmitted to the second print engine in response to a second control signal, thereby coordinating the printing of the first and second side of the paper.
