<h1 class="SECT1"><a name="AEN10529">19.6. <b class=
"APPLICATION">lpq</b> Requests</a></h1>
<p>The RFC1179 protocol specifies that <b class=
"APPLICATION">lpq</b> print status requests can be sent to
the <b class="APPLICATION">lpd</b> server. The lpq requests
have the format:</p>
<div class="INFORMALEXAMPLE">
<a name="AEN10535"></a>
<pre class="SCREEN">
\003printer [id]* \n short
\004printer [id]* \n long
\011printer [id]* \n <b class=
"APPLICATION">LPRng</b> extension- verbose
</pre>
</div>
<br>
<br>
<p>The <b class="APPLICATION">lpd</b> print server will then
return queue status and close the data connection.</p>
<p>RFC1179 does not state in any manner what the format of
the queue status should be. Thus, implementors have been free
to augment or change the status as they like. Even the BSD <b
class="APPLICATION">lpq</b> status format has been changed
from different versions.</p>
<p>See <a href="lpq.htm"><b class="APPLICATION">lpq</b> -
Status Monitoring Program</a> for information on the formats
returned.</p>
<p>The <var class="LITERAL">id</var> values are used to
select the jobs to be displayed. <b class=
"APPLICATION">LPRng</b> displays any job whose ID, hostname,
or user name information from the control file <var class=
"LITERAL">A</var>, <var class="LITERAL">H</var>, or <var
class="LITERAL">P</var> fields match any of the id
values.</p>
<p>Note that since there is no identification of the
information requestor, then restriction of information is
almost impossible.</p>
