Starting up and logging in
Queues window
The Queues window is a dynamic display of the job staging area: jobs are lined up for
processing and printing, some of them are being held waiting for directions, some are
moving from one stage or queue to another and are finally dropped from the list, some
are held for processing by the operator, and some are held in a different queue in case
you need to reprint them.
One approach to understanding the dynamic display is to imagine the three parts of
the Queues window corresponding to the three stages of printing, illustrated as a
downhill flow.
Spooling
—a PostScript or PCL file is saved on the server’s hard disk. The file can come
in packets from the network, or from another place on the server hard disk. Jobs are
added to a queue in the order in which they arrive, and they generally move to another
queue in the same order unless an operator has intervened to change the order.
Rasterizing (RIPping)
—PostScript or PCL commands are interpreted in the GA-1040
to allow the copier to print the file the way its originator intended. The result of this
interpretation is a raster file associated with the original PostScript or PCL file. In this
raster file (raster image), data is associated with each dot that can be rendered by the
print engine.
Printing
—transferring the raster image from the server to the print engine at high
speed, freeing up RAM for the next job. While the PostScript or PCL file is usually
saved to disk, raster images are held in RAM during and after each print job. However,
both users and operators can request that the GA-1040 save the raster image to disk
along with the PostScript or PCL file.
Saving the raster image to disk offers some 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, which means that individual pages of a saved raster file
can be accessed.
