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

336 Normally, printers are set up via a web browser. The
337 <application>Cups</application> server will normally connect via
338 the url http://localhost:631. From there printers, print
339 jobs, and the server configuration can be set up and managed.
340 Remote system administration can also be set up. Configuration
341 can also be done from the command line via the
342 <command>lpadmin</command>, <command>lpoptions</command>,
343 and <command>lpstat</command> commands.
344 </para>
345
346 <para>
347 Configuration of <application>Cups</application> is dependent on
348 the type of printer and can be complex. Generally, PostScript printers
349 are easier. For detailed instructions on configuration and use of
350 <application>Cups</application>, see <ulink

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