33 The Common Unix Printing System (CUPS) is a print spooler and
34 associated utilities. It is based on the "Internet Printing

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

343
344 <para>
345 For non-PostScript printers to print with
346 <application>Cups</application>, you need to install <xref linkend="gs"/>
347 to convert PostScript to raster images and a driver (e.g., from
348 <xref linkend="gutenprint"/>) to convert the resulting raster images to a
349 form that the printer understands.
350 <ulink url="http://www.linuxprinting.org/foomatic.html">Foomatic</ulink>
351 drivers use Ghostscript to convert PostScript to a printable form directly,
352 but this is considered to be a hack by <application>Cups</application>
