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

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

356 <para>
357 For non-PostScript printers to print with

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