With this tutorial we are going to learn how to set orientation for print jobs in a Java Desktop Application. This is a very basic feature, if you want to offer print services inside your application, because it gives the user the ability to choose the orientation of his printing.
In order to set orientation for print jobs you simply have to:
- Open a new pdf file to print using
BufferedInputStream(new FileInputStream("myfile.pdf")). - Create a PDF doc flavor using
DocFlavor.INPUT_STREAM.PDFthat returns aDocFlavorobject. - Use
PrintServiceLookup.lookupDefaultPrintService()to locate the default print service for this environment. - Use
createPrintJob()to create and return aDocPrintJobcapable of handling data from any of the supported document flavors. - Create a class that extends
PrintJobAdapter. - and override printJobCompleted. Then register a listener to the print job to get notified when the job is complete using.
- Set up the
PrintRequestAttributeSetusingHashPrintRequestAttributeSet. - Use
OrientationRequested.PORTRAITorOrientationRequested.LANDSCAPEto set the oriantation.
Let’s see the code:
package com.javacodegeeks.snippets.desktop;
import java.io.BufferedInputStream;
import java.io.FileInputStream;
import java.io.InputStream;
import javax.print.Doc;
import javax.print.DocFlavor;
import javax.print.DocPrintJob;
import javax.print.PrintService;
import javax.print.PrintServiceLookup;
import javax.print.SimpleDoc;
import javax.print.attribute.HashPrintRequestAttributeSet;
import javax.print.attribute.PrintRequestAttributeSet;
import javax.print.attribute.standard.OrientationRequested;
import javax.print.event.PrintJobAdapter;
import javax.print.event.PrintJobEvent;
public class SetOrientationForPrintJob {
private static boolean jobRunning = true;
public static void main(String[] args) throws Exception {
// Open the image file
InputStream is = new BufferedInputStream(new FileInputStream("myfile.pdf"));
// create a PDF doc flavor
DocFlavor flavor = DocFlavor.INPUT_STREAM.PDF;
// Locate the default print service for this environment.
PrintService service = PrintServiceLookup.lookupDefaultPrintService();
// Create and return a PrintJob capable of handling data from
// any of the supported document flavors.
DocPrintJob printJob = service.createPrintJob();
// register a listener to get notified when the job is complete
printJob.addPrintJobListener(new JobCompleteMonitor());
// Construct a SimpleDoc with the specified
// print data, doc flavor and doc attribute set.
Doc doc = new SimpleDoc(is, flavor, null);
boolean portrait = false;
// set up the attributes
PrintRequestAttributeSet attributes = new HashPrintRequestAttributeSet();
if (portrait) {
attributes.add(OrientationRequested.PORTRAIT);
}
else {
attributes.add(OrientationRequested.LANDSCAPE);
}
// Print a document with the specified job attributes.
printJob.print(doc, attributes);
while (jobRunning) {
Thread.sleep(1000);
}
System.out.println("Exiting app");
is.close();
}
private static class JobCompleteMonitor extends PrintJobAdapter {
@Override
public void printJobCompleted(PrintJobEvent jobEvent) {
System.out.println("Job completed");
jobRunning = false;
}
}
}This was an example on how to set orientation for print job.
