That seems to be a bug in ExampleFO2OldStylePrint.java. If you
instantiate the Renderer yourself, you also have to set the user agent.
See additional line below. Sorry for the trouble.

Well, a better way would be support for the Java Printing System (JPS,
available since J2SE 1.4). If you can make it work with the hint above,
good. Otherwise, someone has to implement support for JPS first. It's
on my personal list but I don't have much "fun time" left lately.
