    <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="AEN10556" id="AEN10556"></a>
      <pre class="SCREEN">
\005printer user [id]* \n
</pre>
    </div>

    <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
    <tt class="LITERAL">A</tt>, <tt class="LITERAL">H</tt>, or
    <tt class="LITERAL">P</tt> 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>
