<P>PROBLEM TO BE SOLVED: To execute a printing job by changing the execution order of the print job based on the number of used sheets necessary for executing the print job, the number of stored sheets, and the number of remaining dischargeable sheets. <P>SOLUTION: In an image forming device 1, a job control unit 13 acquires the number of stored sheets stored in a paper sheet tray, and the number of remaining dischargeable sheets up to the limit discharge number of a paper discharge stacker from a print unit 3. A sheet number measuring unit 14 calculates the number of copied sheets to be used by the print job from the print job information including the print page number and the set number of the print job to be sent from upper class devices Pc1-Pcn. A sheet number comparison unit 15 compares the number of copied sheets with the number of stored sheets and the number of remaining dischargeable sheets. The job control unit 13 sets the execution acceptance/rejection of the print job and the execution order of the print job based on the result of comparison, and executes the print of the print job by a print unit 3 based on the print execution acceptance/rejection and the execution order of the print job. <P>COPYRIGHT: (C)2013,JPO&INPIT |
