Printer Component
링크 복사

Available as of Apache Camel 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 Apache Camel 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>

<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>

URI format

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]

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`	`NA_LETTER`	Sets the stationary as defined by enumeration names in the javax.print.attribute.standard.MediaSizeName API API. The default setting is to use North American Letter sized stationary. The value's case is ignored, e.g. values of `iso_a4` and `ISO_A4` may be used.
`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
`mediaTray`	`AUTOSENSE`	Since Camel 2.11.x sets MediaTray supported by the javax.print.DocFlavor API
`printerPrefix`	`null`	Since Camel 2.11.x sets the prefix name of the printer, it is useful when the printer name is not start with //hostname/printer
`sendToPrinter`	`true`	Setting this option to `false` prevents sending of the print data to the printer
`orientation`	`portrait`	Since Camel 2.13.x Sets the page orientation. Possible values: `portrait`, `landscape`, `reverse-portrait` or `reverse-landscape`, based on `javax.print.attribute.standard.OrientationRequested`

Printer Producer

Sending data to the printer is very straightforward and involves creating a producer endpoint that can be sent message exchanges on in route.

RouteBuilder builder = new RouteBuilder() {
    public void configure() {
       from(file://inputdir/?delete=true)
       .to("lpr://localhost/default?copies=2" +
           "&flavor=DocFlavor.INPUT_STREAM&" +
