Desktop publishing (also known as DTP) combines a personal computer, page layout software and a printer to create publications on a small economic scale. Users create page layouts with text, graphics, photos and other visual elements using desktop publishing software such as QuarkXPress, Adobe InDesign, etc.
Desktop publishing began in 1985 with the introduction of PageMaker software from Aldus and the LaserWriter printer from Apple Computer for the Apple Macintosh computer. The ability to create WYSIWYG page layouts on screen and then print pages at crisp 300 ppi resolution was revolutionary for both the typesetting industry as well as the personal computer industry. The term "desktop publishing" is attributed to Aldus Corporation founder Paul Brainerd, who sought a marketing catch-phrase to describe the small size and relative affordability of this suite of products in contrast to the expensive commercial phototypesetting equipment of the day.
