IPS Gateway User’s Guide (5/2002) 1-5
Getting started
Processing considerations
Note the considerations in this section before installing and setting up IPS
Gateway.
Media selection
IPS Gateway allows you to map trays (specified by AFP/IPDS resources
within the host application) to the physical media available in the printer.
The Media Setup tab in IPS Gateway allows you to associate each logical
IPDS (host) tray with a physical media definition in the printer. See “ Media
Setup tab ” for instructions on defining and mapping media.
Spooling versus streaming queue
You can define the IPS Gateway queue as either a spooling queue or a
streaming queue. To determine the best setting for your printing
environment, review the sections below and the “ Segmentation ” section.
Spooling queue
A spooling queue completely spools an IPDS job from IPS Gateway to the
DocuSP queue before printing begins. This results in a delay between the
submission of the job and the printing of the first page. The delay may be
significant for large jobs.
To help improve processing and print time for large jobs sent to a spooled
queue, IPS Gateway provides the Segmentation option, which segments
large jobs into multiple smaller jobs.
For normal job processing, job segmentation should be disabled.
However, Xerox recommends using job segmentation when using a
spooled queue for any job over 500 pages. Although possible within the
software setup, segmentation to a streaming queue is not necessary
since pages are printed as soon as they are received.
Because only one streaming queue can be active at a given time
(depending on your other printing applications), you may elect to run IPS
Gateway to a spooled queue.
Streaming queue
A streaming queue prints pages as they are received, which results in
minimal delay between the time the job is submitted and when printing
begins.
Only one streaming queue can be active in DocuSP at a given time. If a
non-IPS Gateway streaming queue is active when IPS Gateway submits
a job to its streaming queue on DocuSP, IPS Gateway stops processing
and posts an “IPDS Not Ready” message until the other streaming queue
has completed.
Streaming offers a benefit of being more reliable in the area of IPDS job
recovery. See “ IPDS job recovery ” for more information.
