Abstract

See full text

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.
