33 The Common Unix Printing System (CUPS) is a print spooler and
34 associated utilities. It is based on the "Internet Printing
35 Protocol" and provides printing services to most PostScript

352 Normally, printers are set up via a web browser. The
353 <application>Cups</application> server will normally connect via
354 the url http://localhost:631. From there printers, print
355 jobs, and the server configuration can be set up and managed.
356 Remote system administration can also be set up. Configuration
357 can also be done from the command line via the
358 <command>lpadmin</command>, <command>lpoptions</command>,
359 and <command>lpstat</command> commands.
360 </para>
361
362 <para>
363 Configuration of <application>Cups</application> is dependent on
364 the type of printer and can be complex. Generally, PostScript printers
365 are easier. For detailed instructions on configuration and use of
366 <application>Cups</application>, see <ulink
367 url="http://www.cups.org/documentation.php"/>.
368 </para>
369
370 <para>
371 For non-PostScript printers to print with
372 <application>Cups</application>, you need to install <xref
373 linkend="gs"/> to convert PostScript to raster images and a driver
374 (e.g. from <xref linkend="gutenprint"/>) to convert the resulting
375 raster images to a form that the printer understands. <ulink
376 url="http://www.linuxprinting.org/foomatic.html">Foomatic</ulink>
377 drivers use <xref linkend="gs"/> to convert PostScript to a printable
378 form directly, but this is considered suboptimal by
379 <application>Cups</application> developers.
