322 <para>
323 Configuration of <application>Cups</application> is dependent on
324 the type of printer and can be complex. Generally, PostScript printers
325 are easier. For detailed instructions on configuration and use of
326 <application>Cups</application>, see <ulink
327 url="http://www.cups.org/documentation.php"/>. The Software
328 Administrators Manual and Software Users Manual are particularly useful.

330
331 <para>
332 For non-PostScript printers to print with
333 <application>Cups</application>, you need to install <xref linkend="gs"/>
334 to convert PostScript to raster images and a driver (e.g., from
335 <xref linkend="gutenprint"/>) to convert the resulting raster images to a
336 form that the printer understands.
337 <ulink url="http://www.linuxprinting.org/foomatic.html">Foomatic</ulink>
338 drivers use Ghostscript to convert PostScript to a printable form directly,
339 but this is considered to be a hack by <application>Cups</application>
340 developers.
