<p><b>Note:</b> If you are printing to a remote printer, <b class="APPLICATION">LPD</b>
will eventually have to copy files from the local host to the remote host, so the <var
class="OPTION">-s</var> option will save space only on the local spooling directory, not
the remote. It is still useful, though.</p>
</blockquote>
</div>
</dd>

<dd>
<p>Remove the files in the job after copying them to the spooling directory, or after
printing them with the <var class="OPTION">-s</var> option. Be careful with this
option!</p>

<h2 class="SECT2"><a id="PRINTING-LPC" name="PRINTING-LPC">9.5.5 Administering
Printers</a></h2>

<p>As an administrator for your printers, you have had to install, set up, and test them.
Using the <a href="http://www.FreeBSD.org/cgi/man.cgi?query=lpc&sektion=8"><span
class="CITEREFENTRY"><span class="REFENTRYTITLE">lpc</span>(8)</span></a> command, you
can interact with your printers in yet more ways. With <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=lpc&sektion=8"><span
class="CITEREFENTRY"><span class="REFENTRYTITLE">lpc</span>(8)</span></a>, you can</p>

<ul>
<li>
<p>Start and stop the printers</p>
</li>

<li>
<p>Enable and disable their queues</p>
</li>

<li>
<p>Rearrange the order of the jobs in each queue.</p>
</li>
</ul>

<p>First, a note about terminology: if a printer is <span class="emphasis"><i
class="EMPHASIS">stopped</i></span>, it will not print anything in its queue. Users can
still submit jobs, which will wait in the queue until the printer is <span
class="emphasis"><i class="EMPHASIS">started</i></span> or the queue is cleared.</p>

<p>If a queue is <span class="emphasis"><i class="EMPHASIS">disabled</i></span>, no user
(except <tt class="USERNAME">root</tt>) can submit jobs for the printer. An <span
class="emphasis"><i class="EMPHASIS">enabled</i></span> queue allows jobs to be
submitted. A printer can be <span class="emphasis"><i class="EMPHASIS">started</i></span>
for a disabled queue, in which case it will continue to print jobs in the queue until the
queue is empty.</p>

<p>In general, you have to have <tt class="USERNAME">root</tt> privileges to use the <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=lpc&sektion=8"><span
class="CITEREFENTRY"><span class="REFENTRYTITLE">lpc</span>(8)</span></a> command.
Ordinary users can use the <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=lpc&sektion=8"><span
class="CITEREFENTRY"><span class="REFENTRYTITLE">lpc</span>(8)</span></a> command to get
printer status and to restart a hung printer only.</p>

<p>Here is a summary of the <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=lpc&sektion=8"><span
class="CITEREFENTRY"><span class="REFENTRYTITLE">lpc</span>(8)</span></a> commands. Most
of the commands take a <var class="REPLACEABLE">printer-name</var> argument to tell on
which printer to operate. You can use <var class="LITERAL">all</var> for the <var
class="REPLACEABLE">printer-name</var> to mean all printers listed in <tt
class="FILENAME">/etc/printcap</tt>.</p>

<div class="VARIABLELIST">
<dl>
<dt><tt class="COMMAND">abort <var class="REPLACEABLE">printer-name</var></tt></dt>

<dd>
<p>Cancel the current job and stop the printer. Users can still submit jobs if the queue
is enabled.</p>
</dd>

<dt><tt class="COMMAND">clean <var class="REPLACEABLE">printer-name</var></tt></dt>

<dd>
<p>Remove old files from the printer's spooling directory. Occasionally, the files that
make up a job are not properly removed by <b class="APPLICATION">LPD</b>, particularly if
there have been errors during printing or a lot of administrative activity. This command
finds files that do not belong in the spooling directory and removes them.</p>
</dd>

<dt><tt class="COMMAND">disable <var class="REPLACEABLE">printer-name</var></tt></dt>

<dd>
<p>Disable queuing of new jobs. If the printer is running, it will continue to print any
jobs remaining in the queue. The superuser (<tt class="USERNAME">root</tt>) can always
submit jobs, even to a disabled queue.</p>

<p>This command is useful while you are testing a new printer or filter installation:
disable the queue and submit jobs as <tt class="USERNAME">root</tt>. Other users will not
be able to submit jobs until you complete your testing and re-enable the queue with the
<tt class="COMMAND">enable</tt> command.</p>
</dd>

<dt><tt class="COMMAND">down <var class="REPLACEABLE">printer-name</var> <var
class="REPLACEABLE">message</var></tt></dt>

<dd>
<p>Take a printer down. Equivalent to <tt class="COMMAND">disable</tt> followed by <tt
class="COMMAND">stop</tt>. The <var class="REPLACEABLE">message</var> appears as the
printer's status whenever a user checks the printer's queue with <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=lpq&sektion=1"><span
class="CITEREFENTRY"><span class="REFENTRYTITLE">lpq</span>(1)</span></a> or status with
<tt class="COMMAND">lpc status</tt>.</p>
</dd>

<dt><tt class="COMMAND">enable <var class="REPLACEABLE">printer-name</var></tt></dt>

<dd>
<p>Enable the queue for a printer. Users can submit jobs but the printer will not print
anything until it is started.</p>
</dd>

<dt><tt class="COMMAND">help <var class="REPLACEABLE">command-name</var></tt></dt>

<dd>
<p>Print help on the command <var class="REPLACEABLE">command-name</var>. With no <var
class="REPLACEABLE">command-name</var>, print a summary of the commands available.</p>
</dd>

<dt><tt class="COMMAND">restart <var class="REPLACEABLE">printer-name</var></tt></dt>

<dd>
<p>Start the printer. Ordinary users can use this command if some extraordinary
circumstance hangs <b class="APPLICATION">LPD</b>, but they cannot start a printer
stopped with either the <tt class="COMMAND">stop</tt> or <tt class="COMMAND">down</tt>
commands. The <tt class="COMMAND">restart</tt> command is equivalent to <tt
class="COMMAND">abort</tt> followed by <tt class="COMMAND">start</tt>.</p>
</dd>

<dt><tt class="COMMAND">start <var class="REPLACEABLE">printer-name</var></tt></dt>

<dd>
<p>Start the printer. The printer will print jobs in its queue.</p>
</dd>

<dt><tt class="COMMAND">stop <var class="REPLACEABLE">printer-name</var></tt></dt>

<dd>
<p>Stop the printer. The printer will finish the current job and will not print anything
else in its queue. Even though the printer is stopped, users can still submit jobs to an
enabled queue.</p>
</dd>

<dt><tt class="COMMAND">topq <var class="REPLACEABLE">printer-name</var> <var
class="REPLACEABLE">job-or-username</var></tt></dt>

<dd>
<p>Rearrange the queue for <var class="REPLACEABLE">printer-name</var> by placing the
jobs with the listed <var class="REPLACEABLE">job</var> numbers or the jobs belonging to
<var class="REPLACEABLE">username</var> at the top of the queue. For this command, you
cannot use <var class="LITERAL">all</var> as the <var
class="REPLACEABLE">printer-name</var>.</p>
</dd>

<dt><tt class="COMMAND">up <var class="REPLACEABLE">printer-name</var></tt></dt>

<dd>
<p>Bring a printer up; the opposite of the <tt class="COMMAND">down</tt> command.
Equivalent to <tt class="COMMAND">start</tt> followed by <tt
class="COMMAND">enable</tt>.</p>
</dd>
</dl>
</div>

<p><a href="http://www.FreeBSD.org/cgi/man.cgi?query=lpc&sektion=8"><span

above commands on the command line. If you do not enter any commands, <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=lpc&sektion=8"><span
class="CITEREFENTRY"><span class="REFENTRYTITLE">lpc</span>(8)</span></a> enters an
interactive mode, where you can enter commands until you type <tt
