Setting Printer Margins

When I print a document, MFC changes the origion of the device context to the printable area of a page.  The problem is I can't figure out what this origion is.  Point (0, 0) doesn't refer to the top, left corner of the page.  I've tried using all the CDC Mapping Functions, GetWindowOrg(), GetViewportOrg(), etc, to determine what the origion is set at but they don't appear to return the correct value.

In the CView::OnBeginPrinting(CDC *pDC, CPrintInfo * pInfo)

you could retrieve the margin values from the CDC::Escape method, calling it in that way:

      CPoint      ptPageStart;
      pDC->Escape( GETPRINTINGOFFSET,
                                        0, NULL,
                                        (LPSTR) &ptPageStart);

GetWindowOrg, and GetViewportOrg, don't take in account this margine, and are only referring to the drawable Area.

In that way, the 0,0 origin corresponds to the marginX, marginY point from the Left Top Paper Corner (If you don't change the MapMode)
