File extension ps information

The .PS file extension is a PostScript file type that falls under the category of Vector Image Files. It is an image saved in the PostScript page description language and may also include vector graphics and text. Similar to other file types, this file can be opened using both Mac OS and Windows Programs but unlike them, it can be printed directly using a PostScript printer without it being opened in an application. The PostScript file is usually regarded as an intermediary file between an application and a postscript printer.
PostScript is a language that has been developed by Adobe and it describes the layout of a page or several pages; usually printed. It is dynamically typed and has concatenative programming. It is best applied as a page description language especially in desktop publishing as well as electronic areas. If one comes across files that contain a stream of PostScript data, the files can usually be sent directly to a printer compatible to PostScript in order to be printed. But the more common occurrence is the Encapsulated PostScript files which usually contains a page section or a single graphic.
