Advanced Function Printing (AFP) is an architecture and family of associated printer software and hardware that provides document and information presentation control independent of specific applications and devices. The AFP architecture-based system of hardware and software allows for creating, formatting, viewing, retrieving, printing, and distributing information on a wide variety of printer and display devices. It is an integrated data stream for generating fully composed pages of data. Traditional line-mode print applications compose a line at a time down the page (typically continuous form pages), whereas AFP composes the entire page before printing. In AFP, page elements such as text, images, bar codes, page segments, and overlays, can be specified in any order at any position in the page. This is called all points addressability. Advanced Function Presentation data stream (AFPDS) is a printer-independent data stream that composes full pages within a document. Many of the page elements that can be used with AFP are special objects called resources.
