33 The Common Unix Printing System (CUPS) is a print spooler and
34 associated utilities. It is based on the "Internet Printing
35 Protocol" and provides printing services to most PostScript

355 Configuration of <application>Cups</application> is dependent on
356 the type of printer and can be complex. Generally, PostScript printers
357 are easier. For detailed instructions on configuration and use of
358 <application>Cups</application>, see <ulink
359 url="http://www.cups.org/documentation.php"/>. The Software
360 Administrators Manual and Software Users Manual are particularly useful.

362
363 <para>
364 For non-PostScript printers to print with
365 <application>Cups</application>, you need to install <xref linkend="gs"/>
366 to convert PostScript to raster images and a driver (e.g., from
367 <xref linkend="gutenprint"/>) to convert the resulting raster images to a
368 form that the printer understands.
369 <ulink url="http://www.linuxprinting.org/foomatic.html">Foomatic</ulink>
370 drivers use Ghostscript to convert PostScript to a printable form directly,
371 but this is considered to be a hack by <application>Cups</application>
372 developers.
