Patent ID: 7564584

Claim:
A job processing method of a system which includes an image processing device for executing a printing process of data of a job of a storage unit for storing data of plural jobs, said method comprising the steps of: storing data of plural jobs on a storage unit, wherein data includes at least one of a first job where a first processing condition was set, a second job where the first processing condition was set and a third job where a second processing condition different from the first processing condition was set; analyzing an attribute of each print job stored in the storage unit; adjusting an output schedule of each print job stored in the storage unit so that the print jobs respectively having similar attributes are not continuously printed; said adjusting including: judging whether or not there is a certain bias in the similarity of the attributes of the print jobs; selecting the second sequence in a case where it is judged that there is the certain bias in the similarity of the attributes of the print jobs; and selecting the first sequence in a case where it is judged that there is no certain bias in the similarity of the attributes of the print jobs; causing an image processing device to finish the printing process of the third job after both the printing process of the first job and the printing process of the second job are executed, in a case where the image processing device is operated in a first sequence of the first sequence and a second sequence; and causing the image processing device to start the printing process of the third job before at least the printing process of the second job is finished, in a case where the image processing device is operated in the second sequence of the first sequence and the second sequence.
