AFP is used on IBM Mainframes for page printers. It is an architected presentation function set of the Mixed Object Document Content Architecture (MO:DCA), which is part of IBM’s System Application Architecture.

You don’t actually print with AFP. MO:DCA, IPDS (Intelligent Printer Data Stream) and other is used for printing. The information we have may be out of date, but it used to contain PTOCA (Print Text Object Content Architecture), GOCA (Graphic Object Content Architecture), IOCA (Image Object Content Architecture) as well as some other, non-SAA descriptors (simple image, for example).

IPDS is IBM’s SAA printing language. It handles a variety of bit-mapped fonts, simple graphics primitives, and bit-mapped images. Because of the simplicity of the imaging model, it can be used to drive high speed laser printers.
