Set margins when printing

Question

I have problems to set the margins for printing..
I set margins in this way:
when I start the printing process I do:
        PrinterJob job = PrinterJob.getPrinterJob();
        final Stamp canvas = new Stamp();
        job.setPrintable(canvas);
        MediaPrintableArea area = new MediaPrintableArea(10, 10, 170, 255, MediaPrintableArea.MM);
        HashPrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();
        aset.add(area);
        if (job.printDialog()) { // chiede conferma definitiva
            try {
                job.print(aset);
            } catch (PrinterException ex) {
                Logger.getLogger(Stampa_Try_For_PreciseLocation.class.getName()).log(Level.SEVERE, null, ex);
        }in the canvas class I try to read the margins :
public int print(Graphics g, PageFormat pageFormat, int pageIndex) {
        if (pageIndex >= 1) {
            return Printable.NO_SUCH_PAGE;
        Graphics2D g2 = (Graphics2D) g;
        g2.translate(pageFormat.getImageableX(), pageFormat.getImageableY());
        AffineTransform at = new AffineTransform();
        at.scale(pageFormat.getImageableWidth(), pageFormat.getImageableHeight());
        g2.transform(at);
        double pageWidth = pageFormat.getWidth();
        double pageHeight = pageFormat.getHeight();
        double pageSpUsedX = pageFormat.getImageableX();
        double pageSpUsedY = pageFormat.getImageableY();
        double pageSpUsedWidth = pageFormat.getImageableWidth();
        double pageSpUsedHeight = pageFormat.getImageableHeight();
        System.out.print("larghezza pg = " + pageWidth);
        System.out.println(" ; altezza pg = " + pageHeight);
        System.out.print ("area usabile X = " + pageSpUsedX);
        System.out.println(" ; area usabile Y = " + pageSpUsedY);
        System.out.print("area usabile larghezza  = " + pageSpUsedWidth);
        System.out.println("  ; area usabile altezza = " + pageSpUsedHeight);
        g2.drawString("x as", (float)pageSpUsedX                         , (float)pageSpUsedY);
        g2.drawString("x ad", (float)pageSpUsedX + (float)pageSpUsedWidth, (float)pageSpUsedY);
        g2.drawString("x bs", (float)pageSpUsedX                         , (float)pageSpUsedY + (float)pageSpUsedHeight);
        g2.drawString("x bd", (float)pageSpUsedX+ (float)pageSpUsedWidth , (float)pageSpUsedY + (float)pageSpUsedHeight);
                return Printable.PAGE_EXISTS;
    }But the result is not what I expected to be....
I am working at a program that have to print 'something' on paper's labels
placed in a normal sheet format A4.
and for this purpose it is very important to have the contrlo where the letters are wrote..
I don't know what it is wrong and I need some help..
thank you in advance..

hi Andre,
thank you to answering me,
I tried with your code but still I have not the control that I would have printing.
Perhaps I misunderstand the role and the means of the parameters used for set the printable
area.......
For example.. when I set the margins in this way:
MediaPrintableArea area = new MediaPrintableArea(10, 10, 170, 255, MediaPrintableArea.MM);
I expect to have one area printable with the shape of a rectangle that, on a sheet of
paper A4 format, begin in the corner up to left in the point (5, 10) and have a horizontal size
of 180 millimeters and a vertical size of 265 millimeters.
But this is not happen..., I measured the horizontal side in 150 millimeters (instead 170) and
the vertical size in 248 millimeters (instead 255)....
Measuring the coords of the corner on top to left, I got (5, 13) and not (10, 10).
.....I tried with other values of parameters and never I got the exact values that I expected to have.
Having to print labels glued on a paper sheet - A4 format,
*I need to be sure that when the statement
g2.drawString("x", 0, 0);
is executed
The character x is wrote, on the paper, at the point 10, 10. *
Perhaps
g2.drawString("+", 0, 0);
is not the right operation to get this target..... ????
