打印的简单实现，以及更改打印设置

void PrintTest()

{

CPrintDialog dlg(FALSE, PD_ALLPAGES | PD_COLLATE | PD_NOPAGENUMS | PD_HIDEPRINTTOFILE);

if(dlg.GetDefaults())

{

DEVMODE FAR *pDevMode=(DEVMODE FAR *)::GlobalLock(dlg.m_pd.hDevMode);

pDevMode->dmOrientation=DMORIENT_PORTRAIT;//改为纵向打印

::GlobalUnlock(dlg.m_pd.hDevMode);

DOCINFO di;

memset( &di, 0, sizeof(DOCINFO) );

di.cbSize = sizeof(DOCINFO);

di.lpszDocName = "Printing Test";

di.lpszOutput = (LPTSTR) NULL;

di.fwType = 0;

HDC hDC=dlg.CreatePrinterDC();

CDC dc;

dc.Attach(hDC);

dc.StartDoc(&di);

dc.StartPage();

dc.MoveTo(0,0);

dc.LineTo(1000,1000);

dc.EndPage();

dc.EndDoc();

dc.DeleteDC();

}
