MFC编程打印文本有点小问题，麻烦大佬给看一下

老狗丶

麻烦看下程序咋改才能保证有空格产生啊。

打印代码如下

[C++] 纯文本查看 复制代码

this->UpdateData();

		CString strMessage;
		CString strPrintDevice;

		this->GetDlgItem(IDC_EDIT1)->GetWindowTextW(strMessage);
		strMessage += _T("\r\n");		//添加结尾，方便后面循环读取打印数据

		this->GetDlgItem(IDC_COMBO1)->GetWindowTextW(strPrintDevice);

		DWORD dwFlag = PD_ALLPAGES | PD_NOPAGENUMS | PD_USEDEVMODECOPIES | PD_HIDEPRINTTOFILE;	//打印配置界面的按钮可用性

		CPrintDialog pPrintdlg(FALSE, dwFlag, this);											//CPrintDialog实例化

		HGLOBAL hDevMode = NULL;
		HGLOBAL hDevNames = NULL;
		if (GetPrinterDevice(strPrintDevice.GetBuffer(0), &hDevNames, &hDevMode))				//获得指定打印机的配置、名字
			AfxGetApp()->SelectPrinter(hDevNames, hDevMode);
		else
			AfxMessageBox(_T("Failed to select custom printer"));

		strPrintDevice.ReleaseBuffer();

		pPrintdlg.m_pd.hDevMode = hDevMode;														//让pPrintdlg使用我们指定的打印机
		pPrintdlg.m_pd.hDevNames = hDevNames;

		CDC dc;
		dc.Attach(pPrintdlg.CreatePrinterDC());													//后台打印创建法，如果需要弹出打印对话框，请用DoModal

		DOCINFO di;																				//下面的内容网上很多，就不解释了
		di.cbSize = sizeof(DOCINFO);
		di.lpszDocName = _T("打印测试");
		di.lpszDatatype = NULL;
		di.lpszOutput = NULL;
		di.fwType = 0;

		dc.StartDocW(&di);
		dc.StartPage();
		dc.SetMapMode(MM_TEXT);

		CRect recPrint(0, 0, dc.GetDeviceCaps(LOGPIXELSX), dc.GetDeviceCaps(LOGPIXELSY));
		dc.DPtoLP(&recPrint);
		dc.SetWindowOrg(0, 0);

		CFont newFont;
		VERIFY(newFont.CreatePointFont(120, _T("宋体"), &dc));
		CFont* oldFont = dc.SelectObject(&newFont);

		dc.SetTextAlign(TA_TOP | TA_LEFT);

		CString strPrint;
		int nIndex = 0;
		int x = 50;
		int y = 50;
		CSize textSize;
		textSize = dc.GetTextExtent(_T("00"), 2);							//根据当前字体的宽、高，后面以此高度为行高

		while ((nIndex = strMessage.Find(_T("\r\n"))) > -1)					//将IDC_EDIT1编辑框中内容打印，支持换行，一次换行等于'\r\n'，所以在开头strMessage += _T("\r\n")
		{
			strPrint = strMessage.Left(nIndex);
			strMessage = strMessage.Mid(nIndex + 2);

			dc.TextOutW(x, y, strPrint);

			y += textSize.cy;												//下移一行，行高为字体高度
		}

		dc.SelectObject(oldFont);
		newFont.DeleteObject();
		dc.EndPage();
		dc.EndDoc();
		DeleteDC(dc.Detach());
