desktop publishing, system for producing printed materials that consists of a personal computer or computer workstation, a high-resolution printer (usually a laser printer), and a computer program that allows the user to select from a variety of type fonts and sizes, column justifications, page layouts, and graphics libraries and often includes support for document creation and editing. Desktop publishing enables a small business or an individual to produce professional-quality materials on the premises inexpensively and quickly without the need for outside typesetting or printing facilities.
