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

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

355
356 <para>
357 Configuration of <application>Cups</application> is dependent on
358 the type of printer and can be complex. Generally, PostScript printers
359 are easier. For detailed instructions on configuration and use of

364 <para>
365 For non-PostScript printers to print with
366 <application>Cups</application>, you need to install <xref

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