Abstract: Print jobs may be broken down according to consumable types, job cost categories, and print speed to determine job costing information. Using this information, an operator can see how resources are being used for printing print jobs. After a print job is completed, the total number of pages, an amount of ink, or an amount of toner is allocated to at least one job costing category. Job costing categories include good use of the consumable type or waste. Waste is further broken down into additional job costing categories. This information also is broken into print speeds based on different media types, media trays, or printing devices. This process provides a more holistic overview of the costs incurred to finish a print job.

Abstract: A cloud based server includes user profiles having user policies and an organization policy for printing and scanning operations.
