Method for printing pages within a booklet to improve the appearance of images on opposing pages includes sequencing images such that opposing pages are printed with the same print engine and/or fused the same number of times. Booklets include opposing pages having images fused the same number of times and/or printed with the same print engine as the image on the opposing page.

At least sequential current and subsequent sheets of a print job are received in a document processing system. Each sheet includes a front image and a back image. The received sheets are scheduled to be printed with at least one of a first and a second sequence by at least one of a first and a second marking engine based on a comparison of the image content in corresponding selected portions of each front and back image.

A printing system capable of concurrently processing a plurality of job streams and including one or more marking engines and multiple print media destinations is controlled by a controller that includes a jobs scheduler for determining a schedule for processing queued print jobs using the plurality of concurrent job streams. The job scheduler determines the schedule using a method including: determining a utility function dependent at least upon user preference weighting values, a system model of capabilities of the parallel printing system, and the schedule of the queued print jobs; and optimizing the utility function respective to the schedule of queued print jobs.

A printing system includes a plurality of printers, at least a first and a second of the plurality of printers printing in a first print modality. A scheduling system schedules printing of a set of pages by the plurality of printers. The set of pages, when assembled, may include pages where a high level of consistency is desired, such as facing pages or pages which are otherwise to be placed in close relationship. The scheduling system includes at least two scheduling modes, a first mode in which a consistency constraint is applied to the set of pages, and a second mode, different from the first mode, in which the consistency constraint is not applied. The printing system is configured for printing the set of pages in accordance with the first mode and in accordance with the second mode.

This disclosure provides a printing method and system including two or more integrated image marking engines, wherein the printing system is operated with less than the total number of image marking engines to generate the maximum specified prints per minute associated with the printing system. According to one exemplary embodiment, each image marking engine is controlled to be inactive in a round-robin manner to maintain substantially equal running time on each image marking engine or a substantially equal number of printed sheets on each marking engine.

Described herein is a printing system comprising a plurality of print processing modules which selectively transfer print media therebetween during printing and a system controller that tracks process control protocols of each of the plurality of modules and compares to a scheduled job run and selectively alters a control variable of at least one of the process control protocols thereby preemptively altering initiation of at least one process control protocol to process the job run uninterrupted.
