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

350 Normally, printers are set up via a web browser. The
351 <application>Cups</application> server will normally connect via
352 the url http://localhost:631. From there printers, print
353 jobs, and the server configuration can be set up and managed.
354 Remote system administration can also be set up. Configuration
355 can also be done from the command line via the
356 <command>lpadmin</command>, <command>lpoptions</command>,
357 and <command>lpstat</command> commands.

360 <para>
361 Configuration of <application>Cups</application> is dependent on
362 the type of printer and can be complex. Generally, PostScript printers

368 <para>
369 For non-PostScript printers to print with
370 <application>Cups</application>, you need to install <xref

372 (e.g. from <xref linkend="gutenprint"/>) to convert the resulting
373 raster images to a form that the printer understands. <ulink
374 url="https://wiki.linuxfoundation.org/openprinting/database/foomatic">Foomatic</ulink>
375 drivers use <xref linkend="gs"/> to convert PostScript to a printable
