3-1 8 IPDS User GuideUsing Xerox FreeFlow® Print Server IPS Managerthe print server only supports these features for spooling jobs,and Xerox FreeFlow® Print Server IPDS can only be used withstreaming queues.NOTE: The system can feed inserts and covers from non-fusingtray in response to application commands as described in MapVirtual Trays for Non-Fusing Stock.NOTE: If job accounting on the host is to be accurate and to avoidlimitations of the Save facility with the IPDS jobs, use the Print andRetain feature on the host.Multiple Copy Page Counting Constraints and ConsiderationsThe following considerations apply to the use of the OutputQuantity (multiple copies) feature with IPDS:• Some IPDS hosts may time-out the printer, if a response is notreceived within a certain period of time. Therefore, the usershould only use the Xerox FreeFlow® Print Server OutputQuantity (multiple copies) queue feature for relatively lownumbers of uncollated copies, or a relatively small run ofcollated copies. As a rule of thumb, host commands, ratherthan the print server Output Quantity feature, should be used,if Xerox FreeFlow® Print Server copy processing is likely todelay job processing or page reports for four minutes, or more.• After printing a page, Xerox FreeFlow® Print Server willinclude the page in the count of stacked pages it provides tothe IPDS host. If the printer subsequently prints additionalcopies of the page in response to the print server OutputQuantity setting, it cannot report these additional copies of thepage to the host, since the host does not recognize them, anddoing so would distort the stacked page count. Therefore,once the printer tells the host that all pages in the job havebeen stacked, the host considers the job complete, even if asubstantial number of additional pages remain to be printed tomeet the required output quantity. If there is a failure, after allpages in the job have been reported to the host as stacked,but before all copies have printing, IPDS host recovery will notcause the remaining copies to print, since it will appear to thehost that the job has already completed.• If a failure occurs while Xerox FreeFlow® Print Server isprocessing multiple copies for an IPDS job, additional copieswill be printed for pages retransmitted by the host, even ifcopies were previously created for the page. Depending onwhen the failure occurred, there could be additional copies, upto double the expected number of copies, for all retransmittedpages.\
