Hey,
S.D.Printing.PrintDocument.PrintController has as default a new instance
of S.W.F.PrintControllerWithStatusDialog, which is in SWF assembly.
The current code assigns a new instance of S.D.P.StandardPrintController
to PrintDocument.PrintController, which isn't the right behaviour.
The problem is that it's not a good idea to add System.Windows.Forms as
a reference to the System.Drawing assembly IMHO. So, the approach is to
load the SWD assembly using reflection and then cache the type .ctor.
Also, PrintDocument.PrintController should be never null, and should get
a new PrintControllerWithStatusDialog instance, just like .Net does.
Carlos.
