Answer 2

响应你的按键，写上这段代码
void MyWnd::PrintBaseInfo()
{
CWinApp *pApp = ::AfxGetApp();
CPrintInfo printInfo;
CDC dcPrint; //打印确认对话框
if(pApp->DoPrintDialog(printInfo.m_pPD) != IDOK)
return; ASSERT(printInfo.m_pPD != NULL);
ASSERT(printInfo.m_pPD->m_pd.hDC != NULL); //当前预览页数
printInfo.m_nNumPreviewPages = pApp->m_nNumPreviewPages;
//页码显示方式采用预览方式
VERIFY(printInfo.m_strPageDesc.LoadString(AFX_IDS_PREVIEWPAGEDESC)); DOCINFO docInfo;//打印任务信息
memset(&docInfo, 0, sizeof(DOCINFO));
docInfo.cbSize = sizeof(DOCINFO);
docInfo.lpszDocName = "MyAPP";//打印任务标题 //attach printer dc
dcPrint.Attach(printInfo.m_pPD->m_pd.hDC);  
dcPrint.m_bPrinting = TRUE; //准备开始打印
OnBeginPrinting(&dcPrint, &printInfo); // disable main window
AfxGetMainWnd()->EnableWindow(false); if(!printInfo.m_bDocObject && dcPrint.StartDoc(&docInfo) == SP_ERROR)
{
//初始化失败退出打印
AfxGetMainWnd()->EnableWindow(TRUE);
OnEndPrinting(&dcPrint, &printInfo);
dcPrint.Detach();
AfxMessageBox(AFX_IDP_FAILED_TO_START_PRINT);
return;
} //用户数据用以保存当前打印位置(当前已打印到多少行)
printInfo.m_lpUserData = new int;
memset(printInfo.m_lpUserData, 0, 4); BOOL bError = FALSE;
if (printInfo.m_bDocObject == NULL)
{
for (printInfo.m_nCurPage = 0; 
printInfo.m_bContinuePrinting; 
printInfo.m_nCurPage++)
{
// set up drawing rect to entire page (in logical coordinates)
printInfo.m_rectDraw.SetRect(0, 0, 
dcPrint.GetDeviceCaps(HORZRES),
dcPrint.GetDeviceCaps(VERTRES));
dcPrint.DPtoLP(&printInfo.m_rectDraw);

// attempt to start the current page
if (dcPrint.StartPage() < 0)
{
bError = TRUE;
break;
}

//向打印机DC输出内容
ASSERT(printInfo.m_bContinuePrinting);
OnPrint(&dcPrint, &printInfo); if (dcPrint.EndPage() < 0)
{
bError = TRUE;
break;
}
}
}

// cleanup document printing process
if (!printInfo.m_bDocObject)
{
if (!bError)
dcPrint.EndDoc();
else
dcPrint.AbortDoc();
}

AfxGetMainWnd()->EnableWindow(true);    // enable main window
dcPrint.Detach(); if(printInfo.m_lpUserData != NULL)
{
delete printInfo.m_lpUserData;
printInfo.m_lpUserData = NULL;
}
}//自己再根据需要定制下面的函数
void OnBeginPrinting(CDC* pDC, CPrintInfo* pInfo);
void OnPrint(CDC* pDC, CPrintInfo* pInfo);
void OnEndPrinting(CDC* pDC, CPrintInfo* pInfo);
我想应该可以满足你的打印需求
