Answer: PostScript is a page description language developed by Adobe. It is an interface language output from a desktop system to an output device. It is specifically designed to describe images and text. PostScript describes the images and text on the page using mathematical formulas, and finally translates it into the required output through a PostScript decoder (Interpreter), such as displaying it on the screen, or outputting it on a printer or laser imagesetter. Because the software used in the desktop system includes image software, graphics software, and typesetting software, their functions are also different. So many softwares work together, and they must exchange information according to a certain standard format. Their common standard is the PostScript language. PostScript is the most popular page description language in the world and the de facto industry standard. Its perfect design makes it a choice of equipment from multiple manufacturers and is supported by many software. Almost all prepress output devices support the PS language, and the success of the PS language has also made the open electronic publishing system widely popular in the world. mobile whiteboard,Cork board,portable white boards on wheels Dongguan Aoxing Audio Visual Equipment CO.,Ltd , https://www.aoxingscreen.com
