<p>Much of the flexibility of the <b class=
"APPLICATION">LPRng</b> software is obtained from the ability
to control the details of each step of job processing. The
following section details each step in the processing of a
job, and explains the printcap options used to control each
operation.</p>
<p>Assume the <tt class="LITERAL">pr</tt> printcap entry has
the form:</p>
<div class="INFORMALEXAMPLE">
<a name="AEN6754"></a>
<pre class="SCREEN">
pr
:lp=/dev/lp OR :lp=rp@rm
:sd=/var/spool/lpd/pr
:lf=log
:filter=/usr/local/bin/lpf
</pre>
</div>
<br>
<br>
<p>Assume that we have used the following command to print a
set of files.</p>
<div class="INFORMALEXAMPLE">
<a name="AEN6757"></a>
<pre class="SCREEN">
lpr -Ppr file1 file2
</pre>
</div>
<br>
<br>
<p>This will create a control file in the <tt class=
"FILENAME">/var/spool/lpd/pr</tt> directory with the
following contents (this is an example - in practice there
may be minor differences between the example and an actual
control file):</p>
<div class="INFORMALEXAMPLE">
<a name="AEN6761"></a>
<pre class="SCREEN">
Hh4.private
J/tmp/file1 /tmp/file2
CA
Lpapowell
Ppapowell
fdfA002230h4.private
N/tmp/file1
UdfA002230h4.private
fdfB002230h4.private
N/tmp/file2
UdfB002230h4.private
</pre>
</div>
<br>
<br>
<p>We will refer to this example throughout the following
sections.</p>
<div class="SECT1">
<h1 class="SECT1"><a name="CONFIGSETUP">15.1. Configuration
and Setup Options</a></h1>
<p>Options used:</p>
<ul>
<li>
<p><tt class="LITERAL">ipv6</tt> FLAG <i class=
"EMPHASIS">use IPV6 Network facilities</i></p>
</li>
<li>
<p><tt class="LITERAL">default_tmp_dir=</tt><i class=
"EMPHASIS">temporary directory</i></p>
</li>
<li>
<p><tt class="LITERAL">lockfile=</tt><i class=
"EMPHASIS">lpd server lock file</i></p>
</li>
<li>
<p><tt class="LITERAL">report_server_as=</tt><i class=
"EMPHASIS">server name for status reports</i></p>
</li>
<li>
<p><tt class="LITERAL">spool_dir_perms=</tt><i class=
"EMPHASIS">spool directory permissions</i></p>
</li>
<li>
<p><tt class="LITERAL">spool_file_perms=</tt><i class=
"EMPHASIS">spool file permissions</i></p>
</li>
</ul>
<br>
<br>
<p>The <tt class="LITERAL">ipv6</tt> specifies that the
IPV6 protocol, rather than IPV4 will be used.</p>
<p>The <tt class="LITERAL">lockfile</tt> specifies the
location of the lock file used by the <b class=
"APPLICATION">lpd</b> server. This file has the port number
in the <tt class="LITERAL">lpd_port</tt> value appended to
form a unique lock file name.</p>
<p>The <tt class="LITERAL">spool_dir_perms</tt> and <tt
class="LITERAL">spool_file_perms</tt> (default 0700 and
0600 respectively) values are the (numeric) permissions for
the spool directory and spool files.</p>
<p>The <tt class="LITERAL">report_server_as</tt> option
allows an administrator to masquerade a server with another
name. This could be useful if various load sharing
activities are being carried out, or if there are problems
reconfiguring DNS to cause the correct server name to be
reported.</p>
<p>The <tt class="LITERAL">default_tmp_dir</tt> option
specifies a temporary directory to be used to hold files or
information temporarily if there is no spool directory
available.</p>
