<p>The RFC1179 protocol specifies that <b class=
"APPLICATION">lprm</b> job removal requests can be sent to
the <b class="APPLICATION">lpd</b> server. The lpq requests
have the format:</p>
<div class="INFORMALEXAMPLE">
<a name="AEN10558"></a>
<pre class="SCREEN">
\005printer user [id]* \n
</pre>
</div>
<br>
<br>
<p>The <b class="APPLICATION">lpd</b> print server will
search the specified print queue and remove 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 and for which the user has permission to perform a
removal operation. See <a href="permsref.htm">Permissions and
Authentication</a> for details.</p>
<p>Most RFC1179 compatible spoolers use the user information
in the request as the name of the user which spooled the job.
However, in a network environment this is extremely easy to
fabricate, and is at best a weak type of authentication.</p>
