=== Desktop publishing point === The '''desktop publishing point (DTP point)''' or '''PostScript point''' is defined as {{frac|1|72}} or 0.013{{overline|8}} of an inch, making it equivalent to {{frac|25.4|72}} mm = 0.352{{overline|7}} mm. Twelve points make up a pica, and six picas make an inch. This specification was found in the Xerox Interpress language used for its early digital printers and further developed by [[John Warnock]] and [[Charles Geschke]] when they created [[Adobe Postscript#History|Adobe PostScript]].{{cn|date=December 2024}} It was adopted by Apple Computer as the standard for the [[display resolution]] of the [[Macintosh 128K|original Macintosh]] desktop computer and the print resolution for the [[LaserWriter]] printer.<ref name="tucker"> {{cite book |first=H.
