         <h2><a name="Printer-PrinterComponent"></a>Printer Component</h2>

<p><b>Available as of Camel 2.1</b></p>

<p>The <b>printer</b> component provides a way to direct payloads on a route
to a printer. Obviously the payload has to be a formatted piece of payload in order for the
component to appropriately print it. The objective is to be able to direct specific payloads
as jobs to a line printer in a camel flow.</p>

<p>This component only supports a camel producer endpoint.</p>

<p>The functionality allows for the payload to be printed on a default, local remote
or wirelessly linked printer using the javax printing API under the covers.</p>

<h3><a name="Printer-URIformat"></a>URI format</h3>

<p>Since the URI scheme for a printer has not been standardized (the nearest thing to
a standard being the IETF print standard) and therefore not uniformly applied by vendors,
I have chosen "lpr" as the scheme.</p>

<div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent">
<pre class="code-java">
lpr:<span class="code-comment">//localhost/<span class="code-keyword">default</span>[?options]
</span>lpr:<span class="code-comment">//remotehost:port/path/to/printer[?options]</span>
</pre>
</div></div>

<p>You can append query options to the URI in the following format, <tt>?option=value&amp;option=value&amp;...</tt></p>

<p>Sending data to the printer is very straightfoward and involves directing a creating
a producer endpoint that can be sent message exchanges on a camel route.</p>
