Abstract: Variable data printing operations use static and variable content to create many different documents. An estimation system for printing operations implements accelerated consumable use estimation for variable data printing operations by tagging reused objects having static content. The static content is rendered within the estimation system once and then stored for use in later estimation operations, as needed. Variable content is rendered for each record. Using this process, the estimation system does not need to render reused content repeatedly in providing consumable use estimates.

Abstract: Provided is an information processing system that can restore an old version of a task file via an image forming workflow.
