How to draw a text image for printing in Java?

Question

I'm trying to create an an image file (eg. .bmp) with text printed on it, so that when chosen for print on paper it occupies all the paper (but for a narrow margin). How do you approach such a problem? This is essentially how I've been doing.

final BufferedImage img = new BufferedImage(3500, 2480, BufferedImage.TYPE_BYTE_INDEXED);
    final Graphics2D g2D = img.createGraphics();
    g2D.setBackground(Color.white);
    g2D.clearRect(0, 0, width, height);

    int xPos = 20;
    int yPos = 0;

    int j = 0;
    final int maxMengHeight = height / linesNo;

    int maxFontSize = maxMengHeight;

    while (g2D.getFontMetrics(tempFont).getHeight() > maxMengHeight) {
        tempFont = new Font(font.getFontName(), Font.BOLD, --maxFontSize);
    }
    tempFont = null;

    for (Set<Meaning> batch : testMemo) {
        for (Meaning meng : batch) {
            int fontSize = maxFontSize;

            while ((xPos + g2D.getFontMetrics(expFont).stringWidth(word) + g2D.getFontMetrics(defFont).stringWidth(defLine)) > img.getWidth()) {
                expFont = new Font(font.getFontName(), Font.BOLD, --fontSize);
                defFont = new Font(font.getFontName(), Font.PLAIN, fontSize);
            }
            g2D.setFont(expFont);
            yPos += g2D.getFontMetrics().getAscent();
                g2D.drawString(prefixedExp, xPos, yPos);
                xPos += g2D.getFontMetrics().stringWidth(prefixedExp);
            }
            yPos +=  g2D.getFontMetrics().getDescent();
            xPos = 20;
        }
