Amazingly, it has been nearly two decades since desktop publishing arrived on the scene. The debut of the Apple Macintosh computer and the Hewlett Packard LaserJet printer in 1984, plus Adobe’s introduction of PostScript page description language in 1985, laid the groundwork. Then when the Aldus Corporation introduced PageMaker for the Macintosh and Adobe came out with the first PostScript printer (the Apple Laserwriter), a whole new way of publishing documents was born. (Aldus founder Paul Brainerd is generally credited for coining the phrase desktop publishing.)
