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

342 Normally, printers are set up via a web browser. The
343 <application>Cups</application> server will normally connect via
344 the url http://localhost:631. From there printers, print
345 jobs, and the server configuration can be set up and managed.
346 Remote system administration can also be set up. Configuration
347 can also be done from the command line via the
348 <command>lpadmin</command>, <command>lpoptions</command>,
349 and <command>lpstat</command> commands.
350 </para>
351
352 <para>
353 Configuration of <application>Cups</application> is dependent on
354 the type of printer and can be complex. Generally, PostScript printers
355 are easier. For detailed instructions on configuration and use of
356 <application>Cups</application>, see <ulink
357 url="http://www.cups.org/documentation.php"/>.
358 </para>
359
360 <para>
361 For non-PostScript printers to print with
362 <application>Cups</application>, you need to install <xref
363 linkend="gs"/> to convert PostScript to raster images and a driver
364 (e.g. from <xref linkend="gutenprint"/>) to convert the resulting
365 raster images to a form that the printer understands. <ulink
366 url="http://www.linuxprinting.org/foomatic.html">Foomatic</ulink>
367 drivers use <xref linkend="gs"/> to convert PostScript to a printable
368 form directly, but this is considered suboptimal by
