Printing v2d_view

Thanks,
I have writen a viewer which displays some lines and circles read from a text file.
I have to take a print of it.

I am only using the 2d viewer part of opencascade
I am using win2000, with development on VC6 sp4.

Nazeer

Here is a part of code that I actually found in Opencascade forum
it also does not work.

/*SOURCE CODE FOR PRINTING*/
void myAppView::OnViewPrint()
{
CPrintDialog dlg(FALSE, PD_ALLPAGES | PD_HIDEPRINTTOFILE ,NULL);

if (dlg.DoModal() == IDOK)
{
CString theDevice = dlg.GetDeviceName();
Standard_Integer copies = dlg.GetCopies();
LPDEVMODE devmode = dlg.GetDevMode();
Standard_Real scale = devmode->dmScale;
Standard_Integer orientation = devmode->dmOrientation;
enum WNT_OrientationType casOrient;

switch (orientation)
{
case DMORIENT_PORTRAIT:
casOrient = WNT_OT_PORTRAIT;
break;
case DMORIENT_LANDSCAPE:
casOrient = WNT_OT_LANDSCAPE;
break;
}

Handle(WNT_DDriver) myWNTDriver = new WNT_DDriver((Standard_CString)(LPCTSTR)theDevice,"spool.ps",casOrient,scale,copies);

myView->ScreenCopy(myWNTDriver,Standard_True,scale);
myWNTDriver->Spool(Aspect_PM_NPLOTTER,(Standard_CString)(LPCTSTR)theDevice,Standard_True);
myWNTDriver->Close();

}
}
