<P> The same DTP skills and software used for common paper and book publishing are sometimes used to create graphics for point of sale displays, promotional items, trade show exhibits, retail package designs and outdoor signs . Although what is classified as "DTP software" is usually limited to print and PDF publications, DTP skills aren't limited to print . The content produced by desktop publishers may also be exported and used for electronic media . The job descriptions that include "DTP", such as DTP artist, often require skills using software for producing e-books, web content, and web pages, which may involve web design or user interface design for any graphical user interface . </P> <P> Desktop publishing was first developed at Xerox PARC in the 1970s . A contradictory claim states that desktop publishing began in 1983 with a program developed by James Davise at a community newspaper in Philadelphia . The program Type Processor One ran on a PC using a graphics card for a WYSIWYG display and was offered commercially by Best info in 1984 . (Desktop typesetting with only limited page makeup facilities had arrived in 1978--9 with the introduction of TeX, and was extended in the early 1980s by LaTeX .) The DTP market exploded in 1985 with the introduction in January of the Apple LaserWriter printer, and later in July with the introduction of PageMaker software from Aldus, which rapidly became the DTP industry standard software . Later on, PageMaker overtook Microsoft Word in professional DTP in 1985 . The term "desktop publishing" is attributed to Aldus 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 . </P> <P> Before the advent of desktop publishing, the only option available to most people for producing typed documents (as opposed to handwritten documents) was a typewriter, which offered only a handful of typefaces (usually fixed - width) and one or two font sizes . Indeed, one popular desktop publishing book was entitled The Mac is not a typewriter, and it had to actually explain how a Mac could do so much more than a typewriter . The ability to create WYSIWYG page layouts on screen and then print pages containing text and graphical elements at crisp 300 dpi resolution was revolutionary for both the typesetting industry and the personal computer industry; newspapers and other print publications made the move to DTP - based programs from older layout systems such as Atex and other programs in the early 1980s . </P> <P> Early 1980s desktop publishing was a primitive affair . Users of the PageMaker - LaserWriter - Macintosh 512K system endured frequent software crashes, cramped display on the Mac's tiny 512 x 342 1 - bit monochrome screen, the inability to control letter - spacing, kerning, and other typographic features, and discrepancies between the screen display and printed output . However, it was a revolutionary combination at the time, and was received with considerable acclaim . </P>
