<div class="SECT1">
<h1 class="SECT1"><a name="AEN4566">7.7. Configuring Format
and Displayed Information</a></h1>
<p>The following sections describe options that are used by
the <b class="APPLICATION">lpd</b> server to control how it
will return status information to a <b class=
"APPLICATION">lpq</b> request.</p>
<div class="SECT2">
<h2 class="SECT2"><a name="CLASSINSTATUS">7.7.1. Display
Class Information</a></h2>
<p>Options used:</p>
<ul>
<li>
<p><tt class="LITERAL">class_in_status</tt> FLAG <i
class="EMPHASIS">show class name in status</i></p>
</li>
</ul>
<br>
<br>
<p>Setting the <tt class="LITERAL">class_in_status</tt>
option causes the class name rather than priority to be
displayed in the status information.</p>
</div>
<div class="SECT2">
<h2 class="SECT2"><a name="REVERSELPQFORMAT">7.7.2. Reverse
Short and Long <b class="APPLICATION">lpq</b>
Formats</a></h2>
<p>Options used:</p>
<ul>
<li>
<p><tt class="LITERAL">reverse_lpq_format=</tt> FLAG <i
class="EMPHASIS">reverse <b class="APPLICATION">lpq</b>
status format for specified remote systems</i></p>
</li>
</ul>
<br>
<br>
<p>Various Solaris and other System V implementations
support an RFC1179 interface to remote printers.
Unfortunately, there is a problem in that when they send a
status request, the status format is reversed. That is,
when LONG status format is wanted, they send SHORT, and
vice versa.</p>
<p>The <tt class="LITERAL">reverse_lpq_format=</tt>
specifies a list of printers or IP addresses for which the
<b class="APPLICATION">lpd</b> server will return LONG
status when SHORT is requested, and vice versa. For
example:</p>
<div class="INFORMALEXAMPLE">
<a name="AEN4595"></a>
<pre class="SCREEN">
reverse_lpq_format=*.eng.com,130.192.0.0/16
</pre>
</div>
<br>
<br>
<p>will cause hosts whose Fully Qualified Domain Name
(FQDN) ends in <tt class="FILENAME">eng.com</tt> or from
subnet <tt class="LITERAL">130.192.0.0</tt> to have
reversed status returned.</p>
</div>
<div class="SECT2">
<h2 class="SECT2"><a name="SHORTSTATUS">7.7.3. Status Line
Length and Line Count</a></h2>
<p>Options used:</p>
<ul>
<li>
<p><tt class="LITERAL">return_short_status=</tt><i
class="EMPHASIS">return short <b class=
"APPLICATION">lpq</b> status for specified remote
systems</i></p>
</li>
<li>
<p><tt class="LITERAL">short_status_length=</tt><i
class="EMPHASIS">short <b class="APPLICATION">lpq</b>
status length in lines</i></p>
</li>
</ul>
<br>
<br>
<p>In order to be compatible with non-<b class=
"APPLICATION">LPRng</b> client programs, some
administrators would like <b class="APPLICATION">lpd</b> to
return a short or brief status to normal status
queries.</p>
<p>The <tt class="LITERAL">return_short_status=</tt>
specifies a list of printers or IP addresses for which the
<b class="APPLICATION">lpd</b> server will return an
abbreviated status when LONG status is requested. For
example:</p>
<div class="INFORMALEXAMPLE">
<a name="AEN4620"></a>
<pre class="SCREEN">
return_short_status=*.eng.com,130.192.0.0/16
short_status_length#3
</pre>
</div>
<br>
<br>
<p>will cause hosts whose Fully Qualified Domain Name
(FQDN) ends in <tt class="FILENAME">eng.com</tt> or from
subnet <tt class="LITERAL">130.192.0.0</tt> to get only 3
lines of detailed status returned.</p>
</div>
<div class="SECT2">
<h2 class="SECT2"><a name="FORCELPQSTATUS">7.7.4. <b class=
"APPLICATION">lpq</b> Status Format Determined by
Requesting Host Address</a></h2>
<p>Options used:</p>
<ul>
<li>
<p><tt class="LITERAL">force_lpq_status=</tt><i class=
"EMPHASIS">force <b class="APPLICATION">lpq</b> status
format for specified remote systems</i></p>
</li>
</ul>
<br>
<br>
<p>In order to be compatible with non-<b class=
"APPLICATION">LPRng</b> client programs which are totally
unpredictable, this allows the administrator to specify the
format for <b class="APPLICATION">lpq</b> status when
requests arrive.</p>
<p>The <tt class="LITERAL">force_lpq_status=</tt> specifies
a list of formats and printers or IP addresses for which
the <b class="APPLICATION">lpd</b> server will return
status in the specified format. The entry has the format
<tt class="LITERAL">KEY=list;KEY=list...</tt> where <span
class="ACRONYM">KEY</span> is <tt class="LITERAL">s</tt>
for short and <tt class="LITERAL">l</tt> for long format,
and list is a list of hosts or IP addresses. For
example:</p>
<div class="INFORMALEXAMPLE">
<a name="AEN4645"></a>
<pre class="SCREEN">
force_lpq_status=s=pc*.eng.com,130.192.12.0/24,l=sun*.eng.com
</pre>
</div>
<br>
<br>
<p>will cause hosts whose Fully Qualified Domain Name
(FQDN) matches <tt class="FILENAME">pc*eng.com</tt> or from
subnet <tt class="LITERAL">130.192.12.0</tt> to get short
status returned and hosts which match <tt class=
"FILENAME">sun*.eng.com</tt> get long status.</p>
