Print controller using a job despool token to control the release of print jobs stored in a rasterized job spool

摘要

A print controller and associated methods are disclosed. Some print jobs received in the print controller are stored in a rasterized or ripped job spool. The release of these jobs is coordinated by a control system in the print controller. The control system processes an algorithm to determine a sequence of releasing one or more print jobs stored in the rasterized job spool. The control system generates a job despool token and transmits the job despool token to a rasterized job handling system through the data stream of the raw print jobs (such as through the interpreter). The job despool token follows the normal data stream of print jobs through the print controller to the rasterized job handling system. Responsive to receiving and processing the job despool token, the rasterized job handling system releases the print job from the rasterized job spool to a print queue.
