custom controls: printing

[Tom Eugelink]

Ok, so looking at some examples like http://java.dzone.com/articles/introduction-example-javafx-8
where PrintJob is let lose on a node, JavaFX's PrintJob will either use the screen rendering or -if present- call: public void print(PrinterJob job)

Correct?
