Printer Page edited by willem jiang Printer Component Available as of 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 camel flow. This component only supports a camel 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> 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] You can append query options to the URI in the following format, ?option=value&option=value&... Options Name Default Value Description mediaSize MediaSizeName.NA_LETTER Sets the stationary as defined by enumeration settings in the javax.print.attribute.standard.MediaSizeName 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 Messages to a Printer 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. Usage Samples Example 1: Printing text based payloads on a Default printer using letter stationary and one-sided mode RouteBuilder builder = new RouteBuilder() { public void configure() { from(file://inputdir/?delete=true) .to("lpr://localhost/default?copies=2" + "&flavor=DocFlavor.INPUT_STREAM&" + "&mimeType=AUTOSENSE" + "&mediaSize=na-letter" + "&sides=one-sided") }}; Example 2: Printing GIF based payloads on a Remote printer using A4 stationary and one-sided mode RouteBuilder builder = new RouteBuilder() { public void configure() { from(file://inputdir/?delete=true) .to("lpr://remotehost/sales/salesprinter" + "?copies=2&sides=one-sided" + "&mimeType=GIF&mediaSize=iso-a4" + "&flavor=DocFlavor.INPUT_STREAM") }}; Example 3: Printing JPEG based payloads on a Remote printer using Japanese Postcard stationary and one-sided mode RouteBuilder builder = new RouteBuilder() { public void configure() { from(file://inputdir/?delete=true) .to("lpr://remotehost/sales/salesprinter" + "?copies=2&sides=one-sided" + "&mimeType=JPEG" + "&mediaSize=japanese-postcard" + "&flavor=DocFlavor.INPUT_STREAM") }}; Change Notification Preferences View Online | View Change | Add Comment
