If you use Ctrl-P to bring up the Print dialog, then clicking the Print button in the dialog works fine, but pressing Enter to dismiss the dialog causes printing but also causes the dialog to reappear with a different event created from the menu item. Pressing Esc also causes a new dialog to appear. It is a JavaFX bug (Mac only). See https://javafx-jira.kenai.com/browse/RT-40420
