Changing Printer orientation

Accessing a TPrinter object thru a TPrintDC object, I need to be able to change the printer orientation based on real-time information.  What command / function is it that allows this?  I believe I could get the the orientation using the GetDeviceCaps(DC_ORIENTATION) function, but I have no idea to get it!

Try this:

  TPrinter printer;
  TPrintDialog::TData *dlgData = &printer.GetSetup ();
  DEVMODE *dataIn = (DEVMODE *)dlgData->GetDevMode ();
  dataIn->dmFields |= DM_ORIENTATION;
  dataIn->dmOrientation = DMORIENT_LANDSCAPE;
  printer.Print (this, printout, TRUE);

My actual implementation was as follows:

DEVMODE *devMode = (DEVMODE *)Printer->GetSetup().GetDevMode();
devMode->dmOrientation = Orientation;

//Initialize Printer Dc
DC = new TPrintDC(      Printer->GetSetup().GetDriverName(),
      Printer->GetSetup().GetDeviceName(),
                Printer->GetSetup().GetOutputName(),
      devMode);
