Control of printing/trimming position in saddle-stitching device

An image processing apparatus inputs print data from an external device, and analyzes the input print data. The image processing apparatus rasterizes the print data into first image data on the basis of the analysis result. The image processing apparatus receives status information representing the status of a printing apparatus, temporarily saves the first image data in a holding unit on the basis of the received status information and the analysis result, interrupts a transfer process for the first image data to the printing apparatus, starts the transfer process for second image data to the printing apparatus, and transfers, to the printing apparatus, setting information of the print data that corresponds to the first image data. The printing apparatus determines whether corresponding image data has been received within a predetermined period after reception of the setting information of the print data from the image processing apparatus. The printing apparatus manages a print job based on the setting information as a reservation job on the basis of the determination result. Upon reception of image data of the managed reservation job, the printing apparatus starts a printing process for the image data.

Image processing apparatus

The invention proposes a method for devising a production plan of a product to be produced through multiple production steps having different characteristics in a supply chain across multiple companies and/or multiple factories. The method divides a production step of the product into multiple production steps in advance based on a constraint to be considered when the production plan therefor is devised, defines identifiers for the multiple production steps, prestores the defined identifiers in a storage portion as step identification information, and prestores step information having at least correspondences between the production steps and items. In this case, a calculation processing portion identifies and determines production steps and order of calculations, which are involved in the production of the product, based on the shipping plan information, parts table and step information stored in the storage portion, determines which of first and second production plan calculation algorithms is to be executed based on the order of calculations and based on the step identification information stored for each production step, and calculates the production plan by using the determined algorithm.
