Using Socket API</a></h1>
<p>If the spool queue destination is a remote printer
supporting the Socket API, then you can have <b class=
"APPLICATION">LPRng</b> open a connection directly to the
printer. These include the older Apple printers with TCP/IP
support and the HP JetDirect supported printers.</p>

</pre>
</div>
<ol type="1">
<li>
<p>The <var class="LITERAL">lp=server%port</var> or <var
class="LITERAL">lp=IPaddr%port</var> format specifies
that <b class="APPLICATION">lpd</b> should open a TCP/IP
connection to the remote host and simply transfer
verbatum the files to be printed.</p>
</li>
<li>
<p>The <var class="LITERAL">sh</var> and <var class=
"LITERAL">sf</var> will prevent <b class=
"APPLICATION">lpd</b> from trying to generate banner
pages or put form feeds between jobs.</p>
</li>
</ol>
<br>
<br>
<p>While this is the simplest printcap, it is also the most
dangerous as there is nothing to prevent a malformed job from
being sent to the printer. The next printcap example is much
more robust:</p>

<p>This version will use the <b class=
"APPLICATION">ifhp</b> filter to precondition the printer
and to process jobs. See <a href="ifhp.htm"><b class=
"APPLICATION">ifhp</b> Filter</a> for details. The <b
class="APPLICATION">ifhp</b> filter will perform the
appropriate printer resets, translate job information,
and ensure correct printer operation in the presence of
errors. It will also produce voluminous error messages
and status information.</p>
