Image forming system, apparatus, method and computer readable medium for selecting print requests according to post-processing speeds

Abstract

An image forming system includes: an image forming unit that forms an image on paper sheets, plural post-processors that execute post-processing for paper sheets on which an image has been formed by the image forming unit, a calculator that calculates a waiting period for image forming that post-processing by a post-processor in response to a first print request entails, a selector that selects out of succeeding print requests a print request that requires the use of a different post-processor from the post-processor being used for the first print request as a second print request according to the waiting period calculated by the calculator, and an image forming controller that controls the image forming unit so as to execute image forming in response to the second print request selected by the selector in the waiting period for the image forming in response to the first print request.
