Hi All

I have an issue with print preview dialog Graphics Settings,
when I set Compositing Mode to Source Copy and press OK I get the "Parameter is not valid." error

The Call Stack:

I'm using the following code for print preview
NPrintManager printManager = new NPrintManager(new NDrawingDocument());
printManager.ShowPrintPreview();

It is reproducible on W7, W2k8 R2, W8

Does anyone know how to fix this?

Thanks
