PostScript is a page description language used in the electronic and desktop publishing industries. It is a vector-based language that is device independent, meaning that it can be used on any type of output device. PostScript files are typically created in a vector graphics editor such as Adobe Illustrator or CorelDRAW.
PostScript is used to describe the appearance of a printed page, including the text, graphics, and images. It is a page description language, meaning that it describes the appearance of a page, but does not contain any formatting or layout information. This information is added to the PostScript file by the application that will be used to print the file, such as Adobe Acrobat or Adobe InDesign.
PostScript files can be printed to any type of output device, including laser printers, inkjet printers, and imagesetters. They can also be displayed on screen by using a PostScript viewer such as Ghostview or Preview.
PostScript is a page description language (PDL) developed by Adobe Systems. A PostScript file is a text file that contains a series of commands that describe the appearance of a printed page.
When you print a document from a word processor or other application, the application sends a PostScript file to the printer. The printer interprets the commands in the PostScript file and produces the corresponding printed output.
PostScript is a powerful PDL that provides a great deal of control over the appearance of printed pages. However, it is also a complex language, and it can be difficult to create PostScript files by hand.
Most applications that generate PostScript files do so automatically, and you don’t need to know anything about the language to use them. However, if you’re a power user or developer, it can be helpful to understand the basics of PostScript.
Postscript is a very important page description language. It is a device independent language, which means that it can be used on any output device. Postscript also has a very large number of operators, which gives it great flexibility.
