Printing a frame Scaling problem

[Markus Schmider]

Hello,

I have the requirement to print the frame of a java swing application.
I have implemented the following demo

import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.HeadlessException;
import java.awt.print.PageFormat;
import java.awt.print.Printable;
import java.awt.print.PrinterException;

import javax.swing.JFrame;

public class PrintableFrame extends JFrame implements Printable {

	/**
	 * 
	 */
	private static final long serialVersionUID = -2712034189743271402L;

	@Override
	public int print(Graphics graphics, PageFormat pf, int pageIndex)
			throws PrinterException {
		if (pageIndex > 0) { /* We have only one page, and 'page' is zero-based */
            return NO_SUCH_PAGE;
        }
		

        /* User (0,0) is typically outside the imageable area, so we must
         * translate by the X and Y values in the PageFormat to avoid clipping
         */
        Graphics2D g2d = (Graphics2D)graphics;
        double x = pf.getImageableX();
        double y = pf.getImageableY();
        g2d.translate(x, y);

        /* Now print the window and its visible contents */
        this.printAll(graphics);

        /* tell the caller that this page is part of the printed document */
        return PAGE_EXISTS;
	}

	public PrintableFrame(String name) throws HeadlessException {
		super(name);
		
	}

}


import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.print.Printable;
import java.awt.print.PrinterException;
import java.awt.print.PrinterJob;

public class PrintActionListener implements ActionListener {
	
	
	
	public PrintActionListener(Printable printable) {
		super();
		this.printable = printable;
	}

	private Printable printable;

	@Override
	public void actionPerformed(ActionEvent e) {
		PrinterJob job = PrinterJob.getPrinterJob();
        job.setPrintable(this.printable);
        boolean ok = job.printDialog();
        if (ok) {
            try {
                 job.print();
            } catch (PrinterException ex) {
             
            }
        }

	}

}

import javax.swing.JButton;
import javax.swing.JFrame;

import de.dzbw.gui.PrintActionListener;
import de.dzbw.gui.PrintableFrame;

public class Main {

	public static void main(String[] args) {
		PrintableFrame printableFrame = new PrintableFrame("Hallo");
		printableFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		printableFrame.setSize(250, 100);
		JButton printButton = new JButton("Print me");
		PrintActionListener printActionListener = new PrintActionListener(printableFrame);
		printButton.addActionListener(printActionListener);
		printableFrame.add(printButton);
		printableFrame.setVisible(true);
		
	}

}

This works. However when I use the PrintableFrame in a larger application, the printout is clipped.
How can I scale the image to the size of the used paper?

When I debug the above demo I notice that x and y are both 12.0.
How is the PageFormat in the above example determined?
