Getting started
Segmentation
Before specifying job segmentation, review the job processing
considerations described below.
Spooled versus streaming queue
Segmentation is meant to be used with a spooling queue (not a streaming
queue). When using a spooled queue, IPS Gateway normally requires
that the entire IPDS data stream be received prior to processing and
releasing the data stream to the printer. Segmentation creates a series of
small jobs, allowing the printer to begin printing as soon as the specified
number of pages is received.
Although it is possible to specify segmentation for a streaming queue, it
is not necessary since a streaming queue provides shorter job processing
and print time, and segmentation lengthens the print time.
First In/First Out (FIFO)
The IPS Gateway installation software enables the DocuSP First In/First
Out (FIFO) feature. Enabling FIFO ensures that segmented jobs are
printed in segment sequence by the printer. However, if the printer uses
multiple print queues, all queues use FIFO. Therefore, if you segment a
large job into multiple smaller jobs, your output may be interleaved with
jobs submitted to other queues on the printer.
If the segment order of the output for a segmented job appears to be
incorrect, check the FIFO Job Scheduling setting. An intermittent DocuSP
problem has been observed where the FIFO Job Scheduling setting has
been changed to “off” for no apparent reason. See the DocuSP System
Guide for instructions to verify and change the FIFO Job Scheduling
setting.
Banner pages
If you enable job segmentation and your printer is set up to generate a
banner page for each job, then the printer generates a banner page each
time a segment of the job is printed. To prevent banner pages from
printing between each segment, turn off the Banner Page option; refer to
the DocuSP System Guide for instructions.
Offset stacking for unfinished jobs
If you enable job segmentation and your printer is set up to use the Offset
Stacking option for unfinished jobs, then the printer offsets the stack of
pages each time a segment of a job is printed. To prevent offset stacking
for each segment of a job, disable the Offset Stacking option. Refer to the
DocuSP System Guide for instructions.
NOTE: If you disable Offset Stacking, no jobs will be stacked offset.
