Abstract: Provided is an industrial printing system that enables output with the attribute of a printing apparatus at the distributed destination of production printing in a peer-to-peer manner. An attribute acquisition unit acquires other attribute information supported by other printing apparatus at distributed destination. A table generation unit compares acquired other attribute information with own attribute information supported by own printing apparatus to generate a conversion table that is set with a conversion rule for a mismatched attribute. A processing management unit sends the job to the other print server to request for processing based on generated conversion table so that the job is to be printed by the other printing apparatuses.

Abstract: An image forming apparatus includes: a controller that allows a display device to display a settings screen for setting of a function by a user and executes a job based on a user setting made through the settings screen; and a backup device that backs up as backup data the user setting on a storage device each time the user setting is made. When execution of the job based on the user setting is completed, the controller deletes the user setting from the storage device. When, in newly displaying a settings screen on the display device for another job, the user setting for a function configurable on the settings screen is saved on the storage device, the controller determines the content of the user setting as a content of a setting for the job and allows the display device to display the settings screen showing the content of the setting.
