<p>Try the following commands. The commands appear after the

<p>The <tt class="COMMAND">lpr -V</tt> (Verbose) option
causes <b class="APPLICATION">lpr</b> to print status output.
As you can see from the above lines, it first tries to
connect to the <b class="APPLICATION">lpd</b> server on host
<tt class="LITERAL">localhost</tt>, then sends a print
request (which is accepted), then sends a <i class=
"EMPHASIS">control</i> file containing information about the
job and a <i class="EMPHASIS">data</i> file or files which
are copies of the files to be printed.</p>
<p>If you check the <tt class="FILENAME">/tmp/lp</tt> file
and you will find that a copy of <tt class=
"FILENAME">/tmp/hi</tt> has been written to it. By default,
the <b class="APPLICATION">lpd</b> print spooler acts as a
store and forward system, accepting files to be printed,
holding them in the print queue, and then forwarding them to
the destination system or output device.</p>
<p>You can use the <b class="APPLICATION">lpq</b> command to
view the status of the print job.</p>

<p>If you want to see more status information, use <tt class=

<p>There are different status formats available as well. The
<tt class="COMMAND">lpq -s</tt> (summary) produces a single
line of status per spool queue, while the <tt class=
"COMMAND">lpq -v</tt> (verbose) produces output that is very
suitable for processing with programs such as <b class=
"APPLICATION">Perl</b> or <b class="APPLICATION">awk</b>:</p>
