PPD (PostScript Printer Description)

A PPD (PostScript Printer Description) is a file that acts like a detailed blueprint for a printer. It provides specific information about a printer’s capabilities, such as supported paper sizes, resolutions, color options, and finishing features. When you send a print job, the computer uses the PPD to understand how to best communicate with the printer, ensuring your document prints correctly and with the desired settings. Essentially, it helps the computer and printer "speak the same language," making printing more accurate and efficient.
