The title says it all... I'm having trouble getting printing to work. Here's the printing code I'm using:

package net.worldwizard.lasertank;

import java.awt.Container;
import java.awt.Dimension;
import java.awt.image.BufferedImage;
import java.awt.print.PrinterJob;
import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import javax.imageio.ImageIO;
import javax.print.Doc;
import javax.print.DocFlavor;
import javax.print.DocPrintJob;
import javax.print.PrintException;
import javax.print.PrintService;
import javax.print.SimpleDoc;
import javax.print.attribute.DocAttributeSet;
import javax.print.attribute.HashDocAttributeSet;
import javax.print.attribute.HashPrintRequestAttributeSet;
import javax.print.attribute.PrintRequestAttributeSet;
import javax.swing.JFrame;

public class BoardPrinter {

private BoardPrinter() {
// Do nothing
}

public static void printBoard(JFrame j) {
try {
Container c = j.getContentPane();
Dimension d = c.getPreferredSize();
BufferedImage bi = new BufferedImage(d.width, d.height,
BufferedImage.TYPE_INT_ARGB);
c.paintComponents(bi.createGraphics());
ByteArrayOutputStream baos = new ByteArrayOutputStream();
ImageIO.write(bi, "PNG", baos);
byte[] data = baos.toByteArray();
ByteArrayInputStream bais = new ByteArrayInputStream(data);
PrintRequestAttributeSet pras = new HashPrintRequestAttributeSet();
DocFlavor flavor = DocFlavor.INPUT_STREAM.PNG;
PrinterJob pj = PrinterJob.getPrinterJob();
boolean okay = pj.printDialog(pras);
if (okay) {
PrintService service = pj.getPrintService();
DocPrintJob job = service.createPrintJob();
DocAttributeSet das = new HashDocAttributeSet();
Doc doc = new SimpleDoc(bais, flavor, das);
job.print(doc, pras);
}
} catch (IOException ioe) {
CommonDialogs.showErrorDialog("Printing failed!", "Print GameBoard");
} catch (PrintException pe) {
CommonDialogs.showErrorDialog("Printing failed!", "Print GameBoard");
} catch (NullPointerException npe) {
CommonDialogs.showErrorDialog("Printing failed!", "Print GameBoard");
}
}
}


The CommonDialogs class that's being invoked here is just a convenience class for displaying frequently used dialog boxes. Printing works on the Java end, but when it sends the data to the printer I get an error:
pstopdffilter/pstocupsraster failed with err number -31000
I'm not sure what's going on. :confused:

EDIT 2: Just tried the same printing code on my Windows 7 machine. It works there.
