(@dfn{IPP}).  It provides System V and BSD command-line interfaces, as well
as a Web interface and a C programming interface to manage printers and print
jobs.  It supports printing to both local (parallel, serial, USB) and
networked printers, and printers can be shared from one computer to another.
Internally, CUPS uses PostScript Printer Description (@dfn{PPD}) files to
describe printer capabilities and features, and a wide variety of generic and
device-specific programs to convert and print many types of files.")
