331 Configuration of <application>Cups</application> is dependent on
332 the type of printer and can be complex. Generally, PostScript printers
333 are easier. For detailed instructions on configuration and use of

339 <para>
340 For non-PostScript printers to print with
341 <application>Cups</application>, you need to install <xref linkend="gs"/>
342 to convert PostScript to raster images and a driver (e.g., from
343 <xref linkend="gutenprint"/>) to convert the resulting raster images to a
344 form that the printer understands.
345 <ulink url="http://www.linuxprinting.org/foomatic.html">Foomatic</ulink>
