PostScript Printer Description

PostScript Printer Description (PPD) files describe the capabilities of a printer.

I mean, sure, the Internet Printing Protocol also describes this, but apparently printers need to describe themselves in both formats.

You can find these files bundled with CUPS, and also extract them from your printer.

PPD files probably begin.
