<h1 class="SECT1"><a name="AEN3417">4.15. Print Job Classes,
User Requested Job Priority, and Form Support</a></h1>
<p>The <b class="APPLICATION">LPRng</b> software allows users
to assign a class name to print jobs using the <tt class=
"COMMAND">lpr -Cname</tt> option. This causes the <b class=
"APPLICATION">lpr</b> command to put the line <tt class=
"LITERAL">Cname</tt> in the control file. By default, the
(upper cased) first letter of the class name is used to
assign a user requested priority to the job, with <tt class=
"LITERAL">A</tt> being the default lowest priority and <tt
class="LITERAL">Z</tt> being the highest.</p>
<p>The <tt class=
"LITERAL">ignore_requested_user_priority</tt> printcap option
can be used to ignore the user requested priority and jobs
will be printed in the normal first-in first-out order.</p>
<p><b class="APPLICATION">LPRng</b> also makes use of the
class information to do form support and restrict printing to
a specific set of classes. By default the job class
information is ignored, but the <tt class="COMMAND">lpc
class</tt> command can be used to specify one or more classes
(actually glob patterns) to be printed. This facility can be
used to do support printing of jobs that require a specific
form setup. Here is a simple example of how to use this
facility.</p>
<p>Edit the printcap file so it has contents indicated below,
use <tt class="COMMAND">checkpc -f</tt> to check the
printcap, and then use <tt class="COMMAND">lpc reread</tt> to
restart the <b class="APPLICATION">lpd</b> server.</p>
<div class="INFORMALEXAMPLE">
<a name="AEN3435"></a>
<pre class="SCREEN">
lp:force_localhost
lp:server
:sd=/var/spool/lpd/%P
:lp=lp2@localhost
lp2:force_localhost
lp2:server
:sd=/var/spool/lpd/%P
:lp=/tmp/lp2
</pre>
</div>
Execute the following commands to print the <tt class=
"FILENAME">/tmp/hi</tt> file and observe the results:
<div class="INFORMALEXAMPLE">
<a name="AEN3438"></a>
<pre class="SCREEN">
<tt class="PROMPT">h4: {249} %</tt> <tt class=
"USERINPUT"><b>lpc class lp red</b></tt>

classes printed 'red'
lp@h4.private: class updated
<tt class="PROMPT">h4: {250} %</tt> <tt class=
"USERINPUT"><b>lpq</b></tt>
Printer: lp@h4 (classes red)
Queue: no printable jobs in queue
<tt class="PROMPT">h4: {251} %</tt> <tt class=

<tt class="PROMPT">h4: {252} %</tt> <tt class=

<tt class="PROMPT">h4: {253} %</tt> <tt class=
"USERINPUT"><b>lpr -Cred /tmp/hi</b></tt>
<tt class="PROMPT">h4: {254} %</tt> <tt class=
"USERINPUT"><b>lpq</b></tt>
Printer: lp@h4 (classes red)
Queue: no printable jobs in queue
Holding: 1 held jobs in queue
Server: no server active
Status: job 'papowell@h4+89' removed at 09:30:13.569

holdclass papowell@h4+82 A 82 /tmp/hi 3 09:29:52
</pre>
</div>

<p>As seen in the example, we set the queue class to <tt
class="LITERAL">red</tt>, and then sent a (default) class <tt
class="LITERAL">A</tt> job to the printer. It was not
printed, and is listed with <tt class=
"LITERAL">holdclass</tt> status. We sent another job which
was immediately printed.</p>
<p>We can change the print queue class at any time, and then
new class will then control what jobs are printed. To disable
the class selection, use the <tt class="COMMAND">lpc class
queue off</tt> command.</p>
<div class="INFORMALEXAMPLE">

<pre class="SCREEN">
<tt class="PROMPT">h4: {255} %</tt> <tt class=
