1. 枚举计算机的所有打印机

#include 
     
      PRINTER_INFO_5* prninfo = NULL;void CMFCApplication1Dlg::OnBnClickedButton8(){	DWORD dwNeeded=0, dwReturned=0;	EnumPrinters(PRINTER_ENUM_LOCAL, NULL, 5, NULL, 0, &dwNeeded, &dwReturned);	prninfo = (PRINTER_INFO_5*)GlobalAlloc(GPTR, dwNeeded);	if (EnumPrinters(PRINTER_ENUM_LOCAL, NULL, 5, (LPBYTE)prninfo, dwNeeded,	 &dwNeeded, &dwReturned)) 	 {		for (DWORD i = 0; i < dwReturned; i++, prninfo++) 		{			TRACE(_T("x = %s\n"), prninfo->pPrinterName);			TRACE(_T("x = %s\n"), prninfo->pPortName);		}	}}
     

2.设置默认打印机

TCHAR szPrinterName[1024] = { 0 };GetDlgItemText(IDC_EDIT1, szPrinterName, 1024);BOOL ret = FALSE;ret = SetDefaultPrinter(szPrinterName);if (ret == FALSE)	AfxMessageBox(_T("设置默认打印机失败"));else	AfxMessageBox(_T("设置默认打印机成功"));

3.启动打印机服务

SHELLEXECUTEINFO ShExecInfo = { 0 };ShExecInfo.cbSize = sizeof(SHELLEXECUTEINFO);ShExecInfo.fMask  = SEE_MASK_NOCLOSEPROCESS;ShExecInfo.hwnd   = NULL;ShExecInfo.lpVerb = NULL;ShExecInfo.lpFile = _T("cmd");ShExecInfo.lpParameters = _T("/C net start spooler");ShExecInfo.lpDirectory = NULL;ShExecInfo.nShow       = SW_HIDE;ShExecInfo.hInstApp    = NULL;ShellExecuteEx(&ShExecInfo);WaitForSingleObject(ShExecInfo.hProcess, INFINITE);

4.获取指定打印机的所有纸张

TCHAR szPaperName[30000] = {0};TCHAR str[650] = {0};void CMFCApplication1Dlg::Printerdo1(){	BYTE* pBuffer = NULL;	DWORD dwSize = 0;	DWORD dwNum = 0;	//获得缓冲区大小	::EnumPrinters(PRINTER_ENUM_LOCAL, NULL, 5, pBuffer, dwSize, &dwSize, &dwNum);	pBuffer = new BYTE[dwSize];	//枚举打印机	::EnumPrinters(PRINTER_ENUM_LOCAL, NULL, 5, pBuffer, dwSize, &dwSize, &dwNum);	if (dwNum != 0)	{		//获得打印机信息		PRINTER_INFO_5* pPrinterInfo = (PRINTER_INFO_5*)pBuffer;		LPHANDLE phandle;		HANDLE handle;		handle = malloc(sizeof(HANDLE));		phandle = &handle;		PRINTER_DEFAULTS *printer_defaults;		printer_defaults = (PRINTER_DEFAULTS *)malloc(sizeof(PRINTER_DEFAULTS));		LPWSTR str_printername, str_portname, papername2;		//添加打印机名及端口		str_printername = pPrinterInfo->pPrinterName;		str_portname = pPrinterInfo->pPortName;		int nNeeded = 0;		nNeeded = DeviceCapabilities(str_printername, str_portname, DC_PAPERNAMES, 		                             NULL, NULL);		DeviceCapabilities(str_printername, str_portname, DC_PAPERNAMES, 		                             szPaperName,NULL);		for (int i = 0, j=0; i < nNeeded && szPaperName[j] != 0;)		{						wmemcpy_s(str, 64, (LPCWSTR)(&szPaperName)+j,64);			m_ListPrinter.AddString(str);			TRACE(_T("%s\n"), str);               j += 64;		}	}}

5.获取所有纸张的尺寸

CPoint  pt[107];DeviceCapabilities(str_printername, str_printername, DC_PAPERSIZE, (LPWSTR)&pt, NULL);

6.获取默认打印机的默认纸型和大小

void CMFCApplication1Dlg::OnBnClickedButton13(){	// TODO: 在此添加控件通知处理程序代码	PRINTDLG FAR * pPrintDlg = new PRINTDLG;	//获取当前打印机的设置	if (AfxGetApp()->GetPrinterDeviceDefaults(pPrintDlg))	{	      //获取打印机的两个设置信息结构	      DEVNAMES FAR*lpDevNames=(DEVNAMES FAR *)::GlobalLock(pPrintDlg->hDevNames);	      DEVMODE FAR*lpDevMode =(DEVMODE FAR *)::GlobalLock(pPrintDlg->hDevMode);	      //获取相关信息:驱动服务名,打印机名,端口号	      CString szDriver((LPTSTR)lpDevNames +lpDevNames->wDriverOffset);	      CString szDevice((LPTSTR)lpDevNames +lpDevNames->wDeviceOffset);	      CString szOutput((LPTSTR)lpDevNames +lpDevNames->wOutputOffset);	      HANDLE hPrinter;	      ::OpenPrinter((LPWSTR)(LPCWSTR)szDevice, &hPrinter, NULL);	      ::DocumentProperties(NULL,hPrinter,(LPWSTR)(LPCWSTR)szDevice,lpDevMode,			lpDevMode, DM_IN_BUFFER | DM_OUT_BUFFER);	      // 结构解锁	      ::GlobalUnlock(pPrintDlg->hDevNames);	      ::GlobalUnlock(pPrintDlg->hDevMode);	}	delete pPrintDlg;}
