Research direction

Start by reproducing File → Print in the jMonkeyEngine SDK, then inspect DrawEngine.java at initInfo line 227 and trace the call through BaseDocument.print and Editor.java line 98. Compare the surrounding print and preview flow named in the stack trace. Done means the print preview or print action completes without the reported NullPointerException.
