You ran into bug 4093775 reported to Sun's JDC DB on Nov 18, 1997.
Doesn't seem like they are very brisk fixing it... Someone suggested
to call show() before getPrintJob() to work-around the problem.
Someone else noted that it's actually addNotify() (which is called
by show) which must be called. I've tried your example with show()
and it works -- well, it nearly works... you will run into bug
4046088, reported on Apr 18, 1997, then (getFontMetrics() thowing a
NullPointerException). To fix this, someone suggested to call
g.setFont() bevor drawString(). I tried g.setFont(getFont()) and it
finally printed "Hello World!".
CU,
Stefan
