29 The Common Unix Printing System (CUPS) is a print spooler and
30 associated utilities. It is based on the "Internet Printing
31 Protocol" and provides printing services to most PostScript

297 Normally, printers are set up via a web browser. The
298 <application>Cups</application> server will normally connect via
299 the url http://localhost:631. From there printers, print
300 jobs, and the server configuration can be set up and managed.
301 Remote system administration can also be set up. Configuration
302 can also be done from the command line via the
303 <command>lpadmin</command>, <command>lpoptions</command>,
304 and <command>lpstat</command> commands.
305 </para>
306
307 <para>
308 Configuration of <application>Cups</application> is dependent on
309 the type of printer and can be complex. Generally, PostScript printers
310 are easier. For detailed instructions on configuration and use of
311 <application>Cups</application>, see <ulink
312 url="https://www.cups.org/documentation.html"/>.
313 </para>
314
315 <para>
316 For non-PostScript printers to print with
317 <application>Cups</application>, you need to install <xref
318 linkend="gs"/> to convert PostScript to raster images and a driver
319 (e.g. from <xref linkend="gutenprint"/>) to convert the resulting
320 raster images to a form that the printer understands. <ulink
321 url="https://wiki.linuxfoundation.org/openprinting/database/foomatic">Foomatic</ulink>
322 drivers use <xref linkend="gs"/> to convert PostScript to a printable
323 form directly, but this is considered suboptimal by
324 <application>Cups</application> developers.
