Patent ID: 8547562

Claim:
An image forming device comprising: an operation unit by which a user sets a print job to print an image on a recording sheet; a job executing unit that is configured to execute a print job, the job executing unit consuming print resource through the print job; a receiving unit that is configured to receive a print job from an external device, the print job received at the receiving unit containing information about an amount of print resource to be consumed when executed by the job executing unit; a first determining unit that is configured to determine whether the receiving unit receives a print job while the user is setting another print job by the operation unit; and a second determining unit that is configured to determine whether the print resource remains such that both the received print job and the another print job can be executed when the first determining unit determines that the receiving unit receives the print job while the user is setting the another print job by the operation unit, the second determining unit being further configured to estimate an amount of the print resource necessary for executing the another print job and determine that the print resource remains such that both the received print job and the another print job can be executed when a remaining amount of the print resource is greater than or equal to a sum of the estimated amount of the print resource and an amount of print resource to be consumed for the received print job, wherein the job executing unit sets an order of priority for executing the print job among the received print job and the another print job based on the determination result of the second determining unit.
