A RIP simulation device that enables a rapid grasp of a part having a problem in RIP speed and a specific detail of the problem is achieved. While the RIP prediction screen is displayed on a display unit, the result display control unit causes the display unit to display a sheet number corresponding to a position that is on a line graph representing a predicted RIP time for each sheet and is being designated by an input operation unit. When a sheet number displayed on the display unit is selected by the input operation unit, the result display control unit causes the display unit to display an analysis result screen indicating an analysis result related to the page corresponding to the sheet number on the basis of the correspondence relationship between sheets and pages when print output is actually executed.

An editing device generates a first public key and a first private key, receives a manuscript data encrypted using the first public key from an ordering device, and decrypts the encrypted manuscript data using the first private key. The editing device generates, based on the manuscript data, print data encrypted using a second public key generated in a RIP processing device, and deletes the first private key after finishing execution of a job. Using a third public key, the editing device encrypts a log which shows an execution process of the job, the log including information that a finish processing has been executed. The editing device may store the first private key before starting execution of the job, and may control whether the job is to be executed, based on a job ID received from the ordering device.
