When printing, characters are not an exact number of pixels across.
For example, Monospaced 12 pt characters are about 7.03 pixels across.
This renders stringWidth useless for longer strings as it reports the
number of characters * the width of a single character for a monofont.

Either stringWidth must be fixed to report the actual number of pixels
across for a string, or an additional method must be added to the
FontMetric class to return the fractional width of a character.

The code to demonstrate the bug is:

... page is the printers graphics context ...
Font f = new Font ("Monospaced", Font.PLAIN, 12);
page.setFont (f);
FontMetrics fm = page.getFontMetrics ();
String s = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ";
page.drawString (s, 0, 100);
// Notice the lines gradually go out-of-sync
// from the characters in the string.
for (int cnt = 0 ; cnt <= s.length () ; cnt++)
{
    int x = fm.stringWidth (s.substring (0, cnt));
    page.drawLine (x, 100, x, 150);
}
