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

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

351
352 <para>
353 For non-PostScript printers to print with
354 <application>Cups</application>, you need to install <xref linkend="gs"/>
355 to convert PostScript to raster images and a driver (e.g., from
356 <xref linkend="gutenprint"/>) to convert the resulting raster images to a
357 form that the printer understands.
358 <ulink url="http://www.linuxprinting.org/foomatic.html">Foomatic</ulink>
359 drivers use Ghostscript to convert PostScript to a printable form directly,
360 but this is considered to be a hack by <application>Cups</application>
361 developers.
