Abstract
Abstract A method is provided for producing prints in a printing machine having a marking engine operatively coupled with a finishing device, which finishing device normally requires productivity losses in the marking engine. The method includes the steps of: a) storing a first print job and a second print job; b) printing a first portion of the first print job; c) transmitting the printed first portion of the first print job to the finishing device; d) performing a finishing operation, at the finishing device, on the printed first portion of the first print job; e) during the step d), printing a portion of the second print job; f) transmitting the printed portion of the second print job to a print output area, the print output area being separate from the finishing device; and g) initiating printing of a second portion of the first print job, concurrent with step d), for reducing productivity losses in the marking engine.
