1. A method for producing a booklet from a multiple engine serial duplex printer, comprising: ordering sequentially a first plurality of images on a first printing device; feeding sequentially a plurality of two-sided sheets to the first printing device; printing sequentially on one side of each of the plurality of two-sided sheets a corresponding one of the first plurality of images; ordering sequentially a second plurality of images on a second printing device, such that when the second plurality of images is sequentially printed on a corresponding one of the other side of each of the plurality of two-sided sheets and alternate sheets in the sequence are inverted and stacked with alternate non-inverted sheets, images on opposing sides of the sheets are printed by the same printing device; feeding sequentially the plurality of two-sided sheets to the second printing device; printing sequentially on the other side of each of the plurality of two-sided sheets a corresponding one of the second plurality of images; inverting alternated ones of the plurality of two-sided imaged sheets; and stacking sequentially the inverted sheets and non-inverted sheets, so that images on opposing sides of the sheets are printed by the same printing device.
