PrefaceThis book describes the functions and services associated with the Intelligent Printer Data Stream (IPDS)architecture.

This book is a reference, not a tutorial. It complements individual product publications, but does not describeproduct implementations of the architecture.

Who Should Read This BookThis book is for system programmers and other developers who need such information to develop or adapt aproduct or program to interoperate with other presentation products in an Advanced Function Presentation(AFP) environment.

The Intelligent Printer Data Stream Reference describes the function and composition of elements sent toprinters that support the Intelligent Printer Data Stream (IPDS) architecture. However, this book does notdescribe any specific hardware or licensed programs that implement the IPDS architecture.

This book documents the architecture that encompasses IPDS products available at the time of publication.Use this book in conjunction with your printer documentation to:

• Check for the correct input to an IPDS-supported printer

• Learn about the input to IPDS printers

• Develop print server programs to control IPDS printers

• Support the design of programs that provide input for the data stream; for example, a text formatting program

You should note that the IPDS architecture provides a host-to-printer interface intended to be used byprograms requiring direct control over printers.

AFP Consortium (AFPC)The Advanced Function Presentation (AFP) architectures began as the strategic, general purpose documentand information presentation architecture for the IBM® Corporation. The first specifications and products goback to 1984. Although all of the components of the architecture have grown over the years, the majorconcepts of object-driven structures, print integrity, resource management, and support for high print speedswere built in from the start.

In the early twenty-first century, IBM saw the need to enable applications to create color output that isindependent from the device used for printing and to preserve color consistency, quality, and fidelity of theprinted material. This need resulted in the formation, in October 2004, of the AFP Color Consortium™(AFPCC™). The goal was to extend the object architectures with support for full-color devices includingsupport for comprehensive color management. The idea of doing this via a consortium consisting of theprimary AFP architecture users was to build synergism with partners from across the relevant industries, suchas hardware manufacturers that produce printers as well as software vendors of composition, work flow,viewer, and transform tools. Quickly more than 30 members came together in regular meetings and work groupsessions to create the AFP Color Management Object Content Architecture™ (CMOCA™). A major milestonewas reached by the AFP Color Consortium with the initial official release of the CMOCA specification in May2006.

Since the cooperation between the members of the AFP Color Consortium turned out to be very effective andvaluable, it was decided to broaden the scope of the consortium efforts and IBM soon announced its plans toopen up the complete scope of the AFP architecture to the consortium. In June 2007, IBM's role as founding

iv IPDS Reference

member of the consortium was transferred to the InfoPrint® Solutions Company, an IBM/Ricoh® joint venture.In February 2009, the consortium was incorporated under a new set of bylaws with tiered membership andshared governance resulting in the creation of a formal open standards body called the AFP Consortium(AFPC). Ownership of and responsibility for the AFP architectures was transferred at that time to the AFPConsortium.

Publication HistoryThe IPDS Reference was first published by IBM in 1987 and has had several enhancements and updatessince that time. The first eight editions were published by IBM Corporation and later editions were published bythe AFP Consortium.

This command can be used by a print-driver program to printnon-subvertible security labels.

• The XOH Define Group Boundary command provides a means of grouping pages.• The XOH Specify Group Operation command provides a means of specifying an operation to beperformed on a group of pages. The operation can be performed by a printer or by a pre-processingor post-processing device attached to the printer.

This edition describes the relationship between the IPDS architecture and the new SAA/CCSarchitectures that IBM announced in May 1989. Chapter One describes the function of IPDSarchitecture within Systems Application Architecture®. Chapter Fourteen provides additional detailabout IPDS functional divisions and supplies compliance and migration information.

How to Read the Syntax DiagramsThroughout this book, syntax is described using the following format that shows the syntax of a command in ahorizontal representation followed by a table showing the data of the command. Refer to “NotationConventions” on page 67 and “The IPDS Command Format” on page 70 for a detailed description of thecommand syntax. The syntax includes six basic data types:CODE Architected constantCHAR Character stringBITS Bit stringUBIN Unsigned binarySBIN Signed binaryUNDF Undefined type
