Intelligent Printer Data Stream
Intelligent Printer Data Stream (IPDS) is the host-to-printer data stream used by IBM's System Application Architecture (SAA) for Advanced Function Printing (AFP). The IPDS architecture defines the data stream used by print server programs and device drivers to manage all-points-addressable page printing on a full spectrum of devices from low-end workstation and local area network-attached (LAN-attached) printers to high-speed, high-volume page printers for production jobs, shared printing, and mailroom applications.
