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.

321 Normally, printers are set up via a web browser. The
322 <application>Cups</application> server will normally connect via
323 the url http://localhost:631. From there printers, print
324 jobs, and the server configuration can be set up and managed.
325 Remote system administration can also be set up. Configuration
326 can also be done from the command line via the
327 <command>lpadmin</command>, <command>lpoptions</command>,
328 and <command>lpstat</command> commands.
329 </para>
330
331 <para>
332 Configuration of <application>Cups</application> is dependent on
333 the type of printer and can be complex. Generally, PostScript printers
334 are easier. For detailed instructions on configuration and use of
335 <application>Cups</application>, see <ulink
336 url="http://www.cups.org/documentation.php"/>.
337 </para>
338
339 <para>
340 For non-PostScript printers to print with
341 <application>Cups</application>, you need to install <xref
342 linkend="gs"/> to convert PostScript to raster images and a driver
343 (e.g. from <xref linkend="gutenprint"/>) to convert the resulting
344 raster images to a form that the printer understands. <ulink
345 url="https://wiki.linuxfoundation.org/openprinting/database/foomatic">Foomatic</ulink>
346 drivers use <xref linkend="gs"/> to convert PostScript to a printable
347 form directly, but this is considered suboptimal by
