See sample code in MSDN topic CWinApp::GetPrinterDeviceDefaults .

void CMyApp::SetMonochrome()
{
   PRINTDLG pd;
   pd.lStructSize=(DWORD)sizeof(PRINTDLG);
   BOOL bRet=GetPrinterDeviceDefaults(&pd);
   if(bRet)
   {
      // protect memory handle with ::GlobalLock and ::GlobalUnlock
      DEVMODE FAR *pDevMode=(DEVMODE FAR *)::GlobalLock(m_hDevMode);
      // set monochrome mode
      pDevMode->dmColor=DMCOLOR_MONOCHROME;
      ::GlobalUnlock(m_hDevMode);
   }
}

Try this:

HBITMAP hMonocrome = CreateBitMap( ( WORD )lpbi->biWidth, ( WORD )lpbi->biHeight, 1, 1, NULL) ;  

SetDIBits( hDC, hMonocrome, 0, lpbi->Height, (LPSTR)lpbi + lpbi->biSize + nColors *size0f(RGBQUAD) , (LPBITMAPINFO)lpbi, IB_RGB_COLORS ) ;
