Page description language

A Page Description Language (PDL) is a specialized computer language used to describe the layout and content of a printed page or screen display. It provides detailed instructions to printers and display systems on how to position text, images, and graphics, including font styles, colors, and layout. Common examples include PostScript and PDF. PDLs enable consistent and precise rendering of documents across different devices, ensuring the final output matches the intended design. Essentially, they serve as a blueprint that guides the printing or display process to produce accurate visual representations of digital documents.
