PostScript is a page description language developed by Adobe Systems in the 1980s. It is used primarily for printing and is designed to describe the layout and appearance of text and images on a printed page. This technology allows for high-quality graphics and precise control over how documents are rendered. In addition to printing, PostScript has influenced other technologies, including PDF (Portable Document Format). It enables the creation of complex documents that can be easily shared and printed across different devices and platforms, making it a foundational tool in desktop publishing and graphic design.
