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

339 Normally, printers are set up via a web browser. The
340 <application>Cups</application> server will normally connect via
341 the url http://localhost:631. From there printers, print
342 jobs, and the server configuration can be set up and managed.
343 Remote system administration can also be set up. Configuration
344 can also be done from the command line via the
345 <command>lpadmin</command>, <command>lpoptions</command>,
346 and <command>lpstat</command> commands.

348
349 <para>
350 Configuration of <application>Cups</application> is dependent on
351 the type of printer and can be complex. Generally, PostScript printers

356
357 <para>
358 For non-PostScript printers to print with
359 <application>Cups</application>, you need to install <xref

361 (e.g. from <xref linkend="gutenprint"/>) to convert the resulting
362 raster images to a form that the printer understands. <ulink
363 url="https://wiki.linuxfoundation.org/openprinting/database/foomatic">Foomatic</ulink>
364 drivers use <xref linkend="gs"/> to convert PostScript to a printable
365 form directly, but this is considered suboptimal by
