Introduction
Overview
The primary audience for this document is the system
administrator or the individ ual(s) responsible for managing the
print production environment.
Intelligent Printer Data Stream (IPDS) is a bi-directional print data
stream defined by IBM®. IPDS is a sequence of information
transmitted between a host c omputer and IPDS print er as directed
by a print driver, such as IBM’s Print Service Facility (PSF). In
addition to delivering print description information, the IPDS data
stream performs printer control functions and shares job status
information.
The Xerox FreeFlow® Print Server IPDS software is configu red by
means of a Graphical User Interface (GUI), featuring pul l-down
menus, tabs, and icons from which to manage the Xerox Fre eFlow
Print Server IPDS functions. Xerox FreeFlow Print Server IPDS
supports the TCP/IP and Online Channel interfaces.

Introduction
Features
Xerox FreeFlow® Print Server Support for the IPDS Data Stream
Xerox FreeFlow® Print Server IPDS supports IPDS resulting from
processing of AFP (Advanced Function Presentation) resources
such as print data sets, page definitions, form definitions, page
segments, fonts, and overlays. There are several IBM® data
architectures within the AFP environment that are fully supported
by Xerox FreeFlow Print Server IPDS:
•MO: DCA-P: Mixed Object Document Content Architecture for
presentation
•PTOCA PT1, P T2, and P T3: Presentation Text Object Content
Architecture
•IOCA: Image Object Content Architecture
•GOCA: Graphics Object Content Architecture
Printers
•BCOCA: Bar Code Object Content Architecture
Each of the data ob jects foll ows the same obj ect rule of cont aini ng
delimited fields within the structure fields describing each object.
IPDS commands within the data stream enable the system to
control the media-handling capabilities of the printer and other
operations dealing with paper. The commands also provide the
means for managing the downloading of fonts and stored objects,
such as overlays and page segments th at are required to print an
application.
Xerox FreeFlow Print Server IPDS provides the abil ity to:
•Properly image all supported IPDS resources.
•Recognize and process all required IPDS commands
supported by the Xerox FreeFlow Print Server.
IPDS data stream printing is supported on a variety of Xerox
production devices with Xerox FreeFlow Print Server, including
light production, production monochrome, highlight color, and
color printers .
NOTE: Xerox FreeFlow Print Server IPDS currently does not
support continuous feed printing systems.

2Installation and Setup
The requirements and instructions for installing the Xerox
FreeFlow® Print Server IPDS software and setting up the printing
environment are described in this section. Review this entire
chapter before proceeding with the installation.
Some setup tasks are performed on the print serve r window and
some are performed on the print server IPS Manager. The main
installation and setup tasks are:
•Licensing and configuring the software and features
Xerox FreeFlow® Print Server, version 6.0 or higher.
If your Xerox FreeFlow® Print Server IPDS configuration requires
a channel connection, you will need an online channel board.
Contact your local Xerox representative for more information.
User Access Levels
Access to the IPS Manager is controlled by the print server logon
level. Three user levels ar e avail able to access Xero x Fre eFlow®
Print Server IPS Manager, each with its own level of feature
access.
User/Operator: The User and the Operator have limited access
rights to the IPS Manager. This is the access level assigned when
IPS Manager is first started.
The User or the Operator can do the following:
•Modify and apply settings in the Job Settings, Tray Mappings
and Stacker Mappings tabs, and the System Configuration
window.
•Use the Manage Job Profiles button to invoke the Job Profile
Editor dialog.
•Load a Job Profile through the Job Profile Editor.
IPDS User Guide2- 1
Installation and Setup
•Select Go Online and Go Offline.
•Select S top or Continue.
•Restart IPS Gateway
System Administrator: The system administrator requires a
password and can perform the same functions as the Operator.
Additionally, the system administrator can:
•Capture or replay a Trace file.
•Load, print, or delete resid ent fonts.
Licensing Requirements
The Xerox FreeFlow® Print Server IPDS feature must be licensed
in order for it to func tion.
Your local Xerox representative provides licenses prior to
installation. The Xerox service representative enters the license
string and expiration date for each license, immediately following
the software installation.
Defining the Target Queue in the Print Server
At least one queue must be created on the Xer ox FreeFlow® Pri nt
Server for processing the IPDS data. Queues used for IPDS must
be defined as streaming queues. Refer to the Xerox FreeFlow®
Print Server on-line help for det ails on cre ating a streaming queue .
Setting System Preferences
The system behavior for jobs or s et s tha t exc eed the cap a cit y of a
finisher can be selected in the System Preferences di alog. To
reach this dialog, select [System Preferences] from the System
pull-down on the main GUI. Select the Job Policy tab. Under
Over Limit Finishing, check Pr int Job Unf inished. I f the [Faul t Job]
or [User Intervention] option in the Over Li mit Finishing panel are
selected, when an over limit finis hin g si tuati on is enc ountered, t he
printer informs the host that a print er fault is raised and
intervention is required. This causes the host to stop sending dat a.
In these cases, it is typically necessar y to terminate the job at the
print server. However, terminating the job at the print server does
not clear it from an IPDS host output queue, and the host will
retransmit the data unless the job is also terminated at the host.

Creating an IPDS Target Queue
In the Queue Manager, select [New] from the Queue drop down
menu, or from the short cut icon. Refer to t he foll owing pr operti es
to make selections for IPDS queue.
Settings
Although Xerox FreeFlow® Print Server suppor ts spooling jobs,
as well as streaming for other Printer Descripti on Languages
(PDLs), only streaming is supported for IPDS. This is because
IPDS job recovery is cont rolled by the host, and depends upon the
host receiving messages fro m the printer t elling it when ea ch page
has been printed. This level of host control cannot be achieved
when jobs are spooled.
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.
Installation and Setup
•Select the Input / Format FAB. Under Input, select
[Streaming].
The Limit Ripped Data checkbox in the Input / For mat FAB should
always be left unchecked for queues used for IPDS.
Setting External Finishers in the Printer Manager
Determine if the system contains an external finisher. If the
system contains an external finisher, open the Printer Manager
and select the Finisher tab. Right-click on the external finisher
and select [Properties]. Under Maximum Set Size, the default
setting is 65000. Set the value to the actual maximum set size of
the external finisher, otherwise performance issues may be
encountered.

Managing the Print Queue
Using Queue Overrides
The IPDS information processed by the IPDS gateway is sent to
the Output queue selected in the IPS Manager. Use the Queue
Manager to view and manage the queue properties applied to
jobs. Under the PDL Settings tab, the IPDS FAB on the Queue
Manager dialog may be used to set the res olut ion of the print dat a
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 the print server
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: Setting the Override lock for IPDS will force all job data to
be processed as IPDS, preventing the queue from processing
non-IPDS jobs.
Note that a number of p ri nt server queue properties can affect the
attributes of the printed job. In an IPDS environment, the host is
typically responsible for contr olling the attributes of the printed
data. Changing the attributes of the job could cause Xerox
FreeFlow® Print Server IPDS data to print incor rectly. Setting
queue defaults for such properties does not interfere with the
values selected by the IPS Manager. However, overrides for the
following queue properties must be avoided:
Ordinarily an IPDS printer is expected to report exceptions to the
host when data on a page does not fit within the virtual printable
area (VPA). The following queue attributes are not used in Xerox
FreeFlow® Print Server IPDS VPA calculations and can result in
data being shifted or rotated out of the printable area without
notifying the host.
•Rotation
•Image Shift
•Alignment
KEY POINT: Use the Stock Margins feature for shifting data and
having it used as part of the VPA calculations.
2-4IPDS User Guide
NOTE: If an image shift is done at the IPDS queue level, then the
banner page of the IPDS job will contain the image shift as well.
Therefore, the data on the banner page may be shifted off the
page.
Queue Properties
Following are selections relating to IPDS queues:
Settings
Select the Input / Format Feature Access Button (FAB). Under
Input, select [Streaming].
Output
The default setting for the Output Order is System Specified. For
most products, this is N-1 (Descending) output order.
Installation and Setup
NOTE: This setting can cause a problem if set processing (staple
or some other finishing operation) is not being performed. The
problem occurs because the streaming IPDS jo b may be too large
to receive and re-order . The resul t of this sit uation is that, because
there is no logical end to trigger the r e-order, a portion of the IPDS
job would be received but not print. Unless N-1 is required to
perform set processing, the Output Order should be changed to 1N (Ascending) output order.
PDL Settings
Select the IPDS FAB. Use Resolution to determine the resolution
of the output data sent to the print engine. Only values of 300 and
600 dpi are supported. For print engines t hat do not have native
support for 300 dpi, the output will be simulated.
Halftone Resolution
NOTE: The IPDS Halftone Resolution feature is available only for
all supported monochrome, and highlight color products.
In Advanced Settings window, the resolution and the associated
Halftone are displayed. Select [Setup...] to choose the halftone,
for instance, choose: 53, 85, or 106 li ne per inch screens. The
actual selection of halftones offered depends on the particular
product and resolution. For each resolution setting, select the
halftone to associate from the pull-down menu. When the
Resolution (dpi) is selected, the associated halftone screen will
automatically be used for all jobs until it is changed.
For print resolution values that are also supported by PostScript,
IPDS uses the same default Halftone selection used by
IPDS User Guide2- 5
Installation and Setup
PostScript. For instance, if PostScript uses a default halftone of
106 lpi for 600 dpi, the IPDS tool will use the same halftone value
for Resolution of 600.
