ABSTRACT:
A multi-purpose print platform includes a color print engine with color and black toners and a low-cost-per-page print engine having at least two image development systems in which each of the development systems is associated with a different type of black toner and/or highlight color toners. Jobs that include color and black and/or highlight color pages can be processed by using both print engines. The low-cost-per-page print engine typically is low cost in that it facilitates processing pages at a low per page cost relative to color and/or high cost black print engines while providing the productivity and reliability of a typical black only print engine.
