请教大侠，如何将打印时默认的A4竖打，设置为横打，谢谢！

Question

也就是如何将Ａ４纸由竖放改为横放进行打印，谢谢

Answer 1

在打印代码中设置打印模式:lpDevMode->dmOrientation=DMORIENT_LANDSCAPE; 
lpDevMode->dmFilels|=   dmOrientation ;

Answer 2

LPDEVMODE     lpDevMode;           
if(AfxGetApp()->GetPrinterDeviceDefaults(&pd)) //获得默认的打印机的信息           
{           
      lpDevMode=(LPDEVMODE)GlobalLock(pd.hDevMode);           
      if(lpDevMode)           
       {           
          lpDevMode->dmPaperSize=DMPAPER_A4;     //将打印纸设置为A4           
           lpDevMode->dmOrientation=DMORIENT_LANDSCAPE; //将打印机设置为横向打印。           
           lpDevMode->dmPrintQuality=600;     //打印分辨率为600dpi           
 ResetDC(pd,lpDevMode);                                                                                         }           
            GlobalUnlock(pd.hDevMode);           
                        }       

Answer 3

BOOL CWaveAnalyze5View::OnPreparePrinting(CPrintInfo* pInfo)
{
  LPDEVMODE   pDevMode = pInfo->m_pPD->GetDevMode();     pDevMode->dmOrientation=DMORIENT_LANDSCAPE; //将打印机设置为横向打印。
return DoPreparePrinting(pInfo);
}
