Leopard Technical Q&As: Printing
Device Drivers
The printing system in Mac OS X is based on the Common UNIX Printing System (CUPS). Mac OS X printing supports a wide variety of PostScript and raster printers and offers advanced features such as network job spooling via the Internet Printing Protocol (IPP), PDF and QuickDraw imaging, and high-quality color rendering. The printing system and the device driver subsystem also allow printer drivers and applications to present modular and extensible user interfaces. As a result, developers can take advantage of and extend Apple's interface rather than write extra code to override it. |
