Abstract: A job is sent to a device for processing. The device includes a queue manager for determining the order in which jobs are processed. The queue manager receives the job and assigns the job a queue position. The queue position is alternatively computed either from a priority assigned to the job or the source of the job. The priority is alternatively assigned either by the queue manager based on the source of the job or by a device driver that sends the job to the device. A relative time or order that the job was received may also be used to compute the queue position.
