I've a JasperReports report to be printed on landscape mode on a duplex printer. On this I've to support PCL5 and PCL6 printing drivers.
Searching on the internet, I discovered the following code snippet to do this job:
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.print.Book;
import java.awt.print.PageFormat;
import java.awt.print.Printable;
import java.awt.print.PrinterException;
import java.awt.print.PrinterJob;
import javax.print.PrintService;
import javax.print.attribute.HashPrintRequestAttributeSet;
import javax.print.attribute.PrintRequestAttributeSet;
import javax.print.attribute.standard.OrientationRequested;
import javax.print.attribute.standard.Sides;
public class PrintingTest {
public static void main(String[] args) {
try {
//This are for configuration purpose
String orientation = "LANDSCAPE";
String duplexMode = "LONG_EDGE";
int pageOrientation = 0;
PrintRequestAttributeSet atr = new HashPrintRequestAttributeSet();
if ("Landscape".equals(orientation)) {
atr.add(OrientationRequested.LANDSCAPE);
pageOrientation = PageFormat.LANDSCAPE;
} else if ("Reverse_Landscape".equals(orientation)) {
atr.add(OrientationRequested.REVERSE_LANDSCAPE);
pageOrientation = PageFormat.REVERSE_LANDSCAPE;
} else {
atr.add(OrientationRequested.PORTRAIT);
pageOrientation = PageFormat.PORTRAIT;
}
if ("LONG_EDGE".equals(duplexMode)) {
atr.add(Sides.TWO_SIDED_LONG_EDGE);
} else {
atr.add(Sides.TWO_SIDED_SHORT_EDGE);
}
//Printing to the default printer
PrintService printer = javax.print.PrintServiceLookup
.lookupDefaultPrintService();
//Creating the printing job
PrinterJob printJob = PrinterJob.getPrinterJob();
printJob.setPrintService(printer);
Book book = new Book();
PageFormat pageFormat = printJob.defaultPage();
pageFormat.setOrientation(pageOrientation);
// Appending a exampledocument to the book
book.append(new ExampleDocument(), pageFormat);
// Appending another exampledocument to the book
book.append(new ExampleDocument(), pageFormat);
// Setting the Pageable to the printjob
printJob.setPageable(book);
try {
// Here a could show the print dialog
// printJob.printDialog(atr);
// Here I pass the previous defined attributes
printJob.print(atr);
} catch (Exception PrintException) {
PrintException.printStackTrace();
}
} catch (PrinterException ex) {
ex.printStackTrace();
}
}
public static final int MARGIN_SIZE = 72;
private static class ExampleDocument implements Printable {
public int print(Graphics g, PageFormat pageFormat, int page) {
Graphics2D g2d = (Graphics2D) g;
g2d.translate(pageFormat.getImageableX(),
pageFormat.getImageableY());
// Only on the first two documents...
if (page <= 1) {
// Prints using one inch margin
g2d.drawString("Printing page " + page + " - duplex...",
MARGIN_SIZE, MARGIN_SIZE);
return (PAGE_EXISTS);
}
return (NO_SUCH_PAGE);
}
}
}
This works fine on PCL6, but, when tested on PCL5, I noticed that LONG_EDGE and SHORT_EDGE rules are simple ignored. And that in both cases the job is sent as LONG_EDGE. This would not be a problem, except that Java AWT printing API resolves landscape printing by turning all pages 90º anti-clockwise causing the impression that it was printed on SHORT_EDGE mode.
Obs: I was able to print correctly with both configuration, SHORT_EDGE and LONG_EDGE, in portrait and in landscape, by using the SWT API. But I'm not able to convert the jasper printing request in a SWT compatible printing request.
My question is: has anybody ever confronted this situation? Which solution was given to it?
From my observation I've found these possible solutions:
Instead of letting the AWT turn the page and send a portrait print request, force it to send it as a landscape printing request;
Find a way to, when the page is in landscape mode, invert LONG_EDGE and SHORT_EDGE commands. Observe that for this one I would be obligated to correct the problem in which both are treated as LONG_EDGE requests.
Convert the JasperReports to use SWT printing API.
