Introduction
Understanding Job Flow
In an operator-controlled printing environment, remote users send jobs to the Hold queue of the AR-
P15. Using a job management utility, such as Command WorkStation, or Fiery WebSpooler, the
operator views the list of held jobs and decides when to release each job for processing and printing.
The operator may also intervene during the workflow, stopping jobs as they are processed or printed,
placing jobs on hold for future action, or overriding the user-defined print settings for a job. In some
cases, the operator may even modify a job, duplicating or removing pages, or merging it with pages
from another job before releasing it for printing.
Spooling, Processing, Printing
To understand job flow through the AR-P15, it is helpful to consider the three main stages of printing.
Spooling
Spooling
Processing
Printing
Spooling—When a job file is sent over the network by a remote user or imported from disk, it arrives at
the AR-P15 and spools to a location on the hard disk. After spooling completely, the job is held on the
hard disk, where it awaits further instructions from the operator.
Processing (RIPping)—When the operator releases the job file, it undergoes raster image processing
(RIPping) at the AR-P15. During processing, the job file is interpreted as a raster image. This raster
image contains the data required by the copier to print the job the way its originator intended. In the
raster image, data associated with each dot is rendered on the printer. The raster data tells the printer
whether or not to apply toner to each position on the page.
Printing—After processing, the job typically moves on to the printing stage. During this stage, the
raster image associated with the job is transferred from the AR-P15 to the copier at a high speed. The
copier then renders the raster image onto paper, printing the job.
