Set paper margins size when printing ...

Question

Hi,
I'm using the following code to print an image from a component :
     Settings pageSettings = new Settings();
     pageSettings.setXScaleAsFloat( 0.28f );
     pageSettings.setYScaleAsFloat( 0.28f );
     PagePrintable printable = new PagePrintable( pages[pagActual], pageSettings, false );
     PrinterJob printerJob = PrinterJob.getPrinterJob();
     PageFormat format = printerJob.defaultPage();
//     printerJob.pageDialog( format );
     format.setOrientation(PageFormat.LANDSCAPE);
     printerJob.setPrintable(printable, format);
     printerJob.print();
How can I define the paper margins ?
At this moment I have to use default one inch margins.
Thanks,
Alexandre Gil

You can render on your page in any place you like. In your paint method just use the Graphics.translate() method to set the upper and left margin and then use Graphics2D.transform() and a scaled AffineTransform to adjust the width and height of everything:
public int print(Graphics g, PageFormat format, int pageIndex) {
    Graphics2D g2d = (Graphics2D) g;
    g2d.translate(format.getImageableX(), format.getImageableY());
    AffineTransform at = new AffineTransform();
    at.scale(format.getImageableWidth()//*the width of your stuff*/, format.getImageableHeight()//*the height of your stuff*/);
    g2d.transform(at);
    // all your rendering goes here
}Of course you can use values other than format.getImageable* for the values.
