Defining the DocuSP IPDS queue Installation and setup A queue specifically for processing the IPDS data must be created on the DocuSP. The queue must be defined as a streaming queue. Refer to the DocuSP on-line help for details on creating a streaming queue. Although DocuSP supports spooling jobs, as well as streaming for other Printer Defined Languages (PDLs), only streaming is supported for IPDS. You must select a streaming printer queue in the IPS Manager to be used for IPDS printing. A streaming queue processes and prints pages as they are received, which results in minimal delay between the time the job is submitted and when printing begins. Streaming is more reliable for IPDS job recovery. Only one streaming queue can be active on the DocuSP at a given time. If a user attempts to submit an IPDS job while another streaming job is processing, DocuSP tries to start the job at periodic intervals. The retry attempts continue until the other job completes. The DocuSP UI does not indicate that retries are in progress or that a new IPDS job is waiting to print. If a non-IPDS spooling job is in progress when an IPDS job is received, the IPDS job starts processing automatically once all previously queued spooled jobs are complete. Managing the print queue The DocuSP IPDS data streams processed by the IPS Manager are sent to the IPDS print queue. Use the Queue Manager to view and manage the queue properties applied to jobs. The IPDS tab on the Queue Manager dialog may be used to set the resolution of the print data supplied to the print engine. Values of 300 or 600 dpi may be selected. While you may want to dedicate a queue to IPDS, the queue may still be used for other PDLs, subject to the rules of DocuSP job and queue management. The PDL Format must not be set to override for any PDL other than IPDS for a queue that is used to print IPDS jobs. Note that a number of DocuSP queue properties can affect the attributes of the printed job. The IBM host keeps close track of the number of pages submitted to the DocuSP. However, certain DocuSP queue properties can affect the number of sheets actually printed. In addition, changing the attributes of the job could cause IPDS data to print incorrectly. Setting queue defaults for such properties does not interfere with the values selected by the DocuSP IPS Manager. However, overrides for the following queue properties must be avoided: • Quantity • Collation • Sides Imaged • Pages to Print Xerox DocuSP IPDS User Guide 2-3
