printer, language (AFP) A page description language from

IBM introduced in 1984 initially as Advanced Function

Printing. AFP was first developed for mainframes and then

brought to minicomputers and workstations. It is

implemented on the various platforms by Print ServicesFacility (PSF) software, which generates the native IBM

printer language, IPDS and, depending on the version,

PostScript and LaserJet PCL as well. IBM calls AFP a

"printer architecture" rather than a page description

language.
