How the Spooler Works

When a job is sent over a spooled interface, it is not immediately
processed; instead, it is written to the controller's hard drive or to
RAM disk. Once the entire job is sent, the spooler assigns the job a
Job ID and puts the job at the end of the spooler's job queue. Note
that jobs can be spooled at the same time that normal PostScript
processing is going on.
When the controller is READY/IDLE (that is, no jobs are currently
being processed), the first job in the job queue is processed. Once
this job is processed, it is either deleted from the spooler and
removed from the job queue, or it becomes a HELD job in the job
queue, based on whether you chose to retain the job by setting the
Save Spooled Job option to True in the PPD.
