Using Xerox FreeFlow® Print Server IPS Manager • Enable Image Caching: When On, the printer server caches images included in either a Page Segment or Overlay resource. As the Page Segments or Overlays are included by IPDS pages, caching and reusing the image data makes processing more efficient and results in significant performance gains, especially on full color printers. For optimum results, the Page Segments or Overlays should all be included either at the start or end of each page. Also, if possible, the Page Segments or Overlays should contain image data only. Image caching is applied to all IPDS jobs when enabled. NOTE: For jobs with Page Segment or Overlay resources containing a large number of images which are only used once (non-repeating throughout the IPDS job), set the Image Caching Off. Otherwise, performance degradation can occur associated with the caching of large numbers of images which are not reused. Tray Mappings Functions On the print server, you must define the stock using the Printer Manager, assign each stock definition to a specific physical printer tray, and load the stock in the trays. The stock definitions are communicated to the IPS Manager for mapping to the IPDS trays through the Tray Mappings tab. The IBM® host believes that it is dealing with a printer that has at least eight input trays, or more, if more physical trays are present on the print engine. These input trays may be considered virtual trays for IPS Manager. In the Tray Mappings tab you use stock names to map the stock used for each actual physical tray to the stock name used for each virtual tray used by the host. NOTE: Due to limited media attribute information, LCDS system stocks MAIN, AUX, and AUTO, which are accessible from the Xerox FreeFlow® Print Server Printer Manager, will not appear in the IPS Manager Tray Bin Mapping dialog. Note that stock names are used to simplify selection in the Tray Mappings dialog but that the print server selects stock at print time based on the stock properties as well as the stock name. If you have the print server configured to allow duplicate stock names, check the stock attributes when mapping stocks to make sure the correct version is used by IPS Manager. Refer to the Xerox FreeFlow® Print Server on-line help for more information on using the Tray Mappings tab. The contents of the virtual IPDS trays are reported to the host. • Map IPDS Trays to Stock: Designates which stocks belong in the virtual trays recognized by the host. The Trays column indicates each physical tray that calls for the same stock name 3-8 IPDS User Guide
