How do I access the margins of the paper when using java print?

I am trying to print a JPanel with some drawings on it (overriding paintComponent). The graphics are so big that they won't fit on one page, and so I allow it to span multiple pages. My problem is that if I let the user select the Page Type / Paper Type by calling:

PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();
PageFormat pf = printJob.pageDialog(aset);
printJob.setPrintable(canvas, pf);

      

        
        
        
      

    

When I write my print () method (implementing Printable) in my JPanel class, I can't seem to figure out that you have fields. I use graphics.translate(pageFormat.getImageableX(), pageFormat.getImageableY());

to start drawing at the correct angle (0; 0) and it takes margins into account (i.e. starting over (80; 100) or so). But then it prints the bottom and right edges, which I don't want to do as this negates the user's wishes.

Here is the code for my print () method as a reference, which works great when you don't let the user set the paper (using the default instead):

    Rectangle[] pageBreaks;

    public int print(Graphics graphics, PageFormat pageFormat, int pageIndex) throws PrinterException {
        //Calculate how many pages our print will be
        if(pageBreaks == null){
            double pageWidth = pageFormat.getPaper().getWidth();
            double pageHeight = pageFormat.getPaper().getHeight();

            //Find out how many pages we need
            int numberOfPagesHigh = (int) Math.ceil(size.getHeight()/pageHeight);
            int numberOfPagesWide = (int) Math.ceil(size.getWidth()/pageWidth); 
            pageBreaks = new Rectangle[numberOfPagesHigh*numberOfPagesWide];

            double x = 0;
            double y = 0;
            int curXPage = 0;

            //Calculate what we will print on each page
            for (int i = 0; i < pageBreaks.length; i++){
                double xStart = x;
                double yStart = y;
                x += pageWidth;

                pageBreaks[i] = new Rectangle((int)xStart, (int)yStart, (int)pageWidth, (int)pageHeight);

                curXPage++;
                if (curXPage > numberOfPagesWide){
                    curXPage = 0;
                    x = 0;
                    y += pageHeight;
                }
            }


        }

        if (pageIndex < pageBreaks.length){
            //Cast graphics to Graphics2D for richer API
            Graphics2D g2d = (Graphics2D) graphics;

            //Translate into position of the paper
            g2d.translate(pageFormat.getImageableX(), pageFormat.getImageableY());

            //Setup our current page
            Rectangle rect = pageBreaks[pageIndex];

            g2d.translate(-rect.x, -rect.y);
            g2d.setClip(rect.x, rect.y, rect.width, rect.height);

            //Paint the component on the graphics object
            Color oldBG = this.getBackground();
            this.setBackground(Color.white);
            util.PrintUtilities.disableDoubleBuffering(this);
            this.paintComponent(g2d);
            util.PrintUtilities.enableDoubleBuffering(this);
            this.setBackground(oldBG);

            //Return
            return PAGE_EXISTS;
        }
        else {
            return NO_SUCH_PAGE;
        }
   }
