Available as of Fuse Mediation Router 2.1
The printer 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 Fuse Mediation Router flow.
This component only supports a producer endpoint.
The functionality allows for the payload to be printed on a default printer, named local, remote or wirelessly linked printer using the javax printing API under the covers.
Maven users will need to add the following dependency to their pom.xml
for this component:
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-printer</artifactId>
<version>x.x.x</version>
<!-- use the same version as your Camel core version -->
</dependency>
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, we have chosen "lpr" as the scheme.
lpr://localhost/default[?options] lpr://remotehost:port/path/to/printer[?options]
You can append query options to the URI in the following format,
?option=value&option=value&...
| Name | Default Value | Description |
|---|---|---|
mediaSize
|
MediaSizeName.NA_LETTER
|
Sets the stationary as defined by enumeration settings in the javax.print.attribute.standard.MediaSizeName API API. The default setting is to use North American Letter sized stationary |
copies
|
1
|
Sets number of copies based on the javax.print.attribute.standard.Copies
API |
sides
|
Sides.ONE_SIDED
|
Sets one sided or two sided printing based on the
javax.print.attribute.standard.Sides API |
flavor
|
DocFlavor.BYTE_ARRAY
|
Sets DocFlavor based on the javax.print.DocFlavor API |
mimeType
|
AUTOSENSE
|
Sets mimeTypes supported by the javax.print.DocFlavor API
|
Sending data to the printer is very straightforward and involves creating a producer endpoint that can be sent message exchanges on in route.
