Using the same string and the same font results in a different output on the
printer, when using Graphics2D.drawString() or when using TextLayout.draw().
With the bold font the output of TextLayout.draw() has bolder letters.
With the plain font the difference is very little.
When printing german umlauts with Graphics2D.drawString() the output on the
printer is ok, but when printing with TextLayout.draw() the two points above
the letters are not in the right position. They appear to far to the left.
The following program will demonstrate this.
