IBM Intelligent Printer Data Stream

Intelligent Printer Data Stream (IPDS) is Info Print Solution Company's <a href="/facts/IBM_Systems_Application_Architecture/C00QJr21">Systems Application Architecture</a> host-to-printer data stream for <a href="/facts/Advanced_Function_Presentation/m3A1l9dP">Advanced Function Presentation</a> subsystems. It provides an attachment-independent interface for controlling and managing <a href="/facts/All_points_addressable/Bz3AbzYe">all point addressable</a> (APA) printers that allow the presentation of pages containing an architecturally unlimited mixture of different data types, including text, image, graphics, bar code, and object container. It is used by a variety of Info Print and <a href="/facts/OEM/hmUhIWaS">OEM</a> <a href="/facts/Print_server/4gr2wCYq">print servers</a> that drive all points addressable (APA) page printers. Generally, these printers are at the medium to the high end of the print speed and volume spectrum.
"One of the strengths of IPDS is that independent applications can create source data for each data block. The output of these independent applications is merged at the printer to create an integrated mixed data page."
The IPDS architecture allows for both spooled data and print job management to flow bidirectionally between the print server (or print driver) and the Printer Controller.
Examples of print job management controls are:

<ul><li>Printer resolution</li>
<li>Media jam</li>
<li>Pre- or post-processor exceptions</li>
<li>Storage usage</li>
<li>Paper tray capabilities</li>
<li>Duplexing capabilities</li></ul>
Examples of spooled data can be:

<ul><li>Positioning Information for locating objects within the page</li>
<li><a href="/facts/Fonts/04Q7sE8J">Fonts</a></li>
<li>Text</li>
<li>Images</li>
<li><a href="/facts/Bar_code/Mkh4cCTp">Bar codes</a></li>
<li>Electronic overlays</li></ul>
IPDS data streams are purely used to carry print information and data. This is above the network transport layer (typically <a href="/facts/TCP/IP/KNkxtSpw">TCP/IP</a> or <a href="/facts/Systems_Network_Architecture/NlFaXaBC">SNA</a>) and the supporting hardware <a href="/facts/LAN/edUDxJ6J">LANs</a>, channels, and network controllers.
IPDS carries data and instructions from the print server to the printer in structured fields. The printer controller processes these IPDS commands and returns an acknowledgment to the print server.
Similar to <a href="/facts/Personal_Printer_Data_Stream/c7Ypkfj9">PPDS</a>, IPDS uses binary encoded commands and parameters, but IPDS is not compatible with PPDS.
"IPDS is the 'online' way being used to print AFP (<a href="/facts/Advanced_Function_Presentation/m3A1l9dP">Advanced Function Presentation</a>) documents. They can also be printed using the AFPDS format 'offline'."
