Spooling, processing, and printing
To understand job flow through the Fiery, it is helpful to consider
the three main stages of printing.
Spooling —When a job file is sent over the network by a remote
user or imported from disk, it arrives at the Fiery and spools to a
location on the hard disk drive. After spooling completely, the job
is held on the hard disk drive, 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 Fiery. During
processing, the job file is interpreted as a raster image. This
raster image contains the data required by the printer 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 rendered onto paper, and the job is printed.
While original job files are saved to the Fiery hard disk drive,
raster images are typically deleted after printing. The operator
can issue commands to save and hold the raster image on the
hard disk drive along with the original job file. Saving the raster
image to the hard disk drive offers two advantages: raster files
are already processed, so they print quickly, and each part of the
raster file is still identified with a page in the original document, so
you can access individual pages of a saved raster file.
