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
36 and raster printers.

336 The <application>Cups</application> web interface can be accessed
337 via <ulink url="http://localhost:631"/>. From there, printers
338 and print jobs can be managed, and the server configuration
339 can be changed. Configuration can also be done from the command
340 line using the <command>lpadmin</command>,
341 <command>lpoptions</command> and <command>lpstat</command>
342 commands.

344
345 <para>
346 Configuration of <application>Cups</application> is dependent on
347 the type of printer and can be complex. Generally, PostScript printers
348 are easier. For detailed instructions on configuration and use of

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