Run the following test on OS X:

import java.awt.*;

public class TT {
    public static void main(String args[]) {
        JobAttributes ja = new JobAttributes();
        ja.setDialog(JobAttributes.DialogType.COMMON);
        Toolkit.getDefaultToolkit().getPrintJob(null, "Test Printing", ja, null);
    }
}

It should throw NPE but it doesn't. On a machine with a printer configured it just does show a print dialog.

I tried OS X 10.11 and jdk9 b113 but I guess any Oracle JDK would behave like this on any supported OS X version.
