1 Introduction About This Guide This manual contains the IPDS* configuration menu, lists the command sets and provides error messages. This manual assumes you are familiar with IPDS and programming in IPDS. This book is not a tutorial, it does not explain how to program nor does it describe which applications support which commands. For detailed information, refer to the list below.
Chapter 1 Compatible System Attachments Compatible System Attachments With a twinax interface, you can attach your IPDS-compatible printer to the following systems: • • • • System/36 (SSP 5.1 plus IPDS PRPQ P84094) System/38 (with Rel. 8 System/38 Control Program Facility) AS/400 processor 5294/5394/5494 control units (The coax IPDS emulation is currently not used.
2 Configuring with IPDS Commands Overview This chapter summarizes IPDS, lists control codes, and lists error messages. For detailed information, refer to “Sources of Useful IBM Information” on page 7. The IPDS Emulation IPDS consists of the following command sets, which are defined in more detail beginning on page 13. The Command Sets Text This set contains the commands used to present text information on a page, on a page segment, or on an overlay.
Chapter 2 The IPDS Emulation The Data Towers Most of the IPDS commands contain data fields. The type of data is categorized into the following data towers: Text The Presentation Text Object Content Architecture (PTOCA) commands are a part of the text data tower. This information is necessary to print text in a page, a page segment, or an overlay. IM Image The image data enables the printer to print images in a page, a page segment, or an overlay. IO Image This is not supported.
Processing a Page Page Segment State Page segment data is stored when the printer is in this state. A page segment is a frequently accessed resource; it can be a block of text, images, graphics, or bar codes. Page segments can be a part of an overlay. Any state Some commands can be received in any state.
Chapter 2 The IPDS Emulation Overlay Physical Page (Medium Presentation Space) Block Logical Page Page Segment Figure 2. Processing a Page Blocks contain images, graphics, bar codes, coded fonts, and text. Each block is recognized by specific, functional commands. To print a bar code, for example, Bar Code commands must be in the data stream. As each type of data block is stored in memory, the printer moves from state to state.
The Text Commands The Text Commands The following commands are used to present text blocks in a page, a page segment, or an overlay. Load Equivalence (LE) Byte Count D61D Flag CID Data This command allows the printer to use a single suppression ID for more than one suppression pair. Write Text (WT) Byte Count D62D Flag CID Presentation Text Object; Content Architecture control codes and character data Use this command to send character data and controls to the printer.
Chapter 2 The IPDS Emulation Table 1.
Scalable Fonts Scalable Fonts In addition to the IBM 4028 and 3816 bitmap fonts, the IPDS functionality also uses Scalable AGFA fonts. The following table lists available fonts and their mappings from IBM Font Global Identifiers to AGFA numbers. Table 2.
Chapter 2 The IPDS Emulation Images The physical page is the actual medium used, such as a continuous form or an 8 1/2 x 11 inch sheet of paper. The logical page is mapped onto the physical page; you can set its size and position inside the physical page. The logical page contains the image blocks, text blocks, segment and overlay blocks. A block is an area where the image is mapped to. The image presentation space contains the image that will be mapped to the block.
Graphics Write Image (WI) Byte Count D64D Flag CID Data This command is used to denote image data to be printed. Graphics Graphics contain line drawings, such as arcs and lines. The area containing the entire drawing is called the graphics presentation space. Usually, only a part of the drawing will be printed. This part is referred to as the graphics presentation space window.
Chapter 2 The IPDS Emulation The Graphics Command Set The following commands are used to present graphics in a page, a page segment, or an overlay.
The Bar Code Command Set The Bar Code Command Set The following commands are used to present bar codes in a page, a page segment, or an overlay. Write Bar Code Control (WBCC) Byte Count D680 Flag CID Bar Code Area Position; Bar Code Output Control; Bar Code Data Descriptor Use this command to set the bar code block position, size, and orientation; to set the bar code presentation size; the bar code to be used; and to set how the bar code presentation space will map into the bar code block.

The Overlay Command Set The Overlay Command Set Overlays contain data that is frequently accessed and can be stored by name for future use. You can create an overlay so that it fills the entire page or fills part of a page. The following overlay commands are used to access printer data by name and merge on the logical page.
Chapter 2 The IPDS Emulation Begin Page (BP) Byte Count D6AF Flag CID Data This command indicates the beginning of a page and causes the printer to enter the page state. End Byte Count D65D Flag CID Binary Data This command notes the end of a block containing: an image, graphics, or bar codes. End Page (EP) Byte Count D6BF Flag CID Binary Data This command notes the end of a page, a page segment, or an overlay and returns the printer to the home state.
The Device Control Commands No Operation (NOP) Byte Count D603 Flag CID Data This command tells the printer to perform no operation. Sense Type and Model (STM) Byte Count D6E4 Flag CID This command asks the printer to identify its capabilities. The printer responds with one or more Acknowledge Replies, which contain general information and command set vectors that identify supported IPDS function sets and subsets.

Chapter 2 The IPDS Emulation Set Home State (SHS) Byte Count D697 Flag CID Data SHS instructs the printer to return to the home state. If the printer is in the process of printing (in page state), the current page ends and prints the data up to the time of the SHS command. Depending when the SHS command was sent, either a complete or partially completed page prints.
The Device Control Commands Execute Order Home State (XOH) Byte Count D68F Flag CID Data (Code and Parameters) The following orders are valid only when the printer receives them in the home state. The XOH command identifies these orders. Table 6. Execute Order Home State Commands Order Function Hex Code Erase Residual Print Data Prevents access to resident print data. 0500 Obtain Printer Characteristics Used for Acknowledge Replies.

Chapter 2 The IPDS Emulation Exception Processing and IDs Unlike some other protocols, IPDS allows the host to control exception (error) processing, which can free up the printer cpu. The host can request one of two methods: • • the printer must print the pages as requested the printer does not allow any page that has a data stream error to print The first method applies for situations such as printing checks; the second method applies for printing drafts or when troubleshooting the data streams.

D Glossary Acknowledge Reply A message about printer information or exceptions that the printer sends to the host. It can be a positive or negative reply. ([N]ACK can contain status resource or counter information.) bar code A printed code consisting of parallel bars of varied width and spacing and designed to be read by a onedimensional scanning device. bar code block It is a rectangular space that has a specified size, position, and orientation on a logical page.
Appendix D default A value, parameter, attribute, or option assigned by a program or system if another is not specified by the user. deferred printing The printer prints page by page: It gathers all of the page descriptor commands and data blocks for each page and then prints the page. diagnostic Pertains to the detection and isolation of printer malfunctions or mistakes. emulation Refers to the ability of a printer to execute the commands of another printer language (protocol).
graphics presentation space window You can specify a part of the presentation space to be mapped to the graphics block. This portion is called the graphics presentation space window. Specifying a window is synonymous to cropping or trimming. home state The initial state of the printer before it begins downloading overlays, page segments, and/or fonts. After the printer prints the page, the printer returns to the home state.
Appendix D no operation This command causes the printer not to process anything, but instead, to proceed to the next command sequence. object Another term for a font, graphics, image, text, or a combination of these. offset An offset is a measurement indicating displacement. For example, you can specify the logical page to rest in the lower left hand corner of the physical page. ordered printing The printer behaves like a line printer: It begins printing as soon as you send the data.
port A channel used for receiving data from or transmitting data to one or more external devices. presentation space A space where data can be generated before it is mapped onto the logical page. The presentation space uses an X-axis and Y-axis to specify addresses. protocol A set of rules or conventions governing the exchange of information between computer systems. For computer printers, a protocol is the coding convention used to convey and print data.
