When I remove the call above (runModalPrintOperation...) then it prints ok.
The documentation says: "Overrides of printShowingPrintPanel: can invoke this
method."
Is this a documentation error, and it should be: "Overrides of
printShowingPrintPanel: prior to Lion can invoke this method. In Lion it should
NOT be used." ?
Or am I just confused?
