IPS Gateway User’s Guide (5/2002) 1-7Getting startedSegmentationBefore specifying job segmentation, review the job processingconsiderations described below.Spooled versus streaming queueSegmentation is meant to be used with a spooling queue (not a streamingqueue). When using a spooled queue, IPS Gateway normally requiresthat the entire IPDS data stream be received prior to processing andreleasing the data stream to the printer. Segmentation creates a series ofsmall jobs, allowing the printer to begin printing as soon as the specifiednumber of pages is received.Although it is possible to specify segmentation for a streaming queue, itis not necessary since a streaming queue provides shorter job processingand print time, and segmentation lengthens the print time.First In/First Out (FIFO)The IPS Gateway installation software enables the DocuSP First In/FirstOut (FIFO) feature. Enabling FIFO ensures that segmented jobs areprinted in segment sequence by the printer. However, if the printer usesmultiple print queues, all queues use FIFO. Therefore, if you segment alarge job into multiple smaller jobs, your output may be interleaved withjobs submitted to other queues on the printer.If the segment order of the output for a segmented job appears to beincorrect, check the FIFO Job Scheduling setting. An intermittent DocuSPproblem has been observed where the FIFO Job Scheduling setting hasbeen changed to “off” for no apparent reason. See the DocuSP SystemGuide for instructions to verify and change the FIFO Job Schedulingsetting.Banner pagesIf you enable job segmentation and your printer is set up to generate abanner page for each job, then the printer generates a banner page eachtime a segment of the job is printed. To prevent banner pages fromprinting between each segment, turn off the Banner Page option; refer tothe DocuSP System Guide for instructions.Offset stacking for unfinished jobsIf you enable job segmentation and your printer is set up to use the OffsetStacking option for unfinished jobs, then the printer offsets the stack ofpages each time a segment of a job is printed. To prevent offset stackingfor each segment of a job, disable the Offset Stacking option. Refer to theDocuSP System Guide for instructions.NOTE: If you disable Offset Stacking, no jobs will be stacked offset.
