下面是设置横向纵向，设置页面大小的话就是改动pDevMode->dmPaperSize; dmPaperLength\ dmPaperWidth，还有dmFields;，具体改动参见以下DEVMODE结构体

/* 设置系统打印模式
#define DMORIENT_PORTRAIT 1 //纵向
#define DMORIENT_LANDSCAPE 2 //横向 */
/************************************************************************/

void SetLandscapeMode(int PrintMode)
{
PRINTDLG pd;
pd.lStructSize=(DWORD)sizeof(PRINTDLG);
BOOL bRet=AfxGetApp()->GetPrinterDeviceDefaults(&pd);
if(bRet)
{
// protect memory handle with ::GlobalLock and ::GlobalUnlock
DEVMODE FAR *pDevMode=(DEVMODE FAR *)::GlobalLock(pd.hDevMode);
// set orientation to landscape
if(PrintMode==1)//纵向打印
pDevMode->dmOrientation=DMORIENT_PORTRAIT;
else if(PrintMode==2)//横向打印
pDevMode->dmOrientation=DMORIENT_LANDSCAPE;
::GlobalUnlock(pd.hDevMode);
}
}
