At least it's the expected behavior. The event notification happens
synchronously (as the listener should be able to e.g. modify the
document before it gets printed) so it must happen in OOo's main thread.
Stopping this thread will deadlock the whole application.

Why do you want to "sleep" in your listener? Perhaps you can avoid that.
Without understanding what you are trying to achieve it's hard to give
any useful hints.
