Queue to Queue and Redirecting Queues</a></h1>
<p>The <tt class="COMMAND">lpc move</tt> command is used to
move jobs in one queue to another queue on an individual
basis, while the <tt class="COMMAND">lpc redirect</tt>
command redirects all incoming jobs to a new queue. 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">

<pre class="SCREEN">

Execute the following commands to print the <tt class=

<p>We first stop the queues so that the jobs will remain in
them. We then use the <tt class="COMMAND">lpc move fromqueue
id toqueue</tt> command to select a job in the <span class=
"emphasis"><i class="EMPHASIS">fromqueue</i></span> and move
it to the <span class="emphasis"><i class=
"EMPHASIS">toqueue</i></span>. A list of job numbers, job
IDs, or glob patterns to match job IDs can be used to select
the job.</p>
<p>The <tt class="COMMAND">lpc redirect fromqueue
toqueue</tt> will cause all incoming jobs to be redirected to
the specified queue. You can execute the following commands
and observe the results.</p>
<div class="INFORMALEXAMPLE">
