PostScript
PostScript is a page description language and programming language used primarily for describing the appearance of text, graphics, and images on printed pages or digital displays. It is a stack-based, Turing-complete language that enables precise control over layout and rendering, commonly used in printers, publishing software, and graphic design applications. Developed by Adobe in the 1980s, it serves as the foundation for PDF (Portable Document Format) and remains influential in digital printing and document processing.
Developers should learn PostScript when working with low-level document generation, printer drivers, or legacy publishing systems, as it provides direct control over page layout and graphics rendering. It is particularly useful for creating custom print workflows, understanding PDF internals, or developing applications in graphic design and prepress industries where precise typography and vector graphics are critical. Knowledge of PostScript also aids in debugging complex document issues or integrating with hardware that uses PostScript interpreters.
