标准方法是用： EnumPrinters() 函数获取

#define PRINTER_ENUM_DEFAULT     0x00000001
#define PRINTER_ENUM_LOCAL       0x00000002
#define PRINTER_ENUM_CONNECTIONS 0x00000004
#define PRINTER_ENUM_FAVORITE    0x00000004
#define PRINTER_ENUM_NAME        0x00000008
#define PRINTER_ENUM_REMOTE      0x00000010
#define PRINTER_ENUM_SHARED      0x00000020
#define PRINTER_ENUM_NETWORK     0x00000040

BOOL EnumPrinters(
  _In_   DWORD Flags, // 打印机获取方式，见上表 
  _In_   LPTSTR Name,
  _In_   DWORD Level,//PRINTER_INFO_1, PRINTER_INFO_2 , PRINTER_INFO_4, and PRINTER_INFO_5  分别对应1，2，4，5
  _Out_  LPBYTE pPrinterEnum,//A pointer to a buffer that receives an array of PRINTER_INFO_1, PRINTER_INFO_2, PRINTER_INFO_4, orPRINTER_INFO_5 structures.                             // Each structure contains data that describes an available print object.
  _In_   DWORD cbBuf,//The size, in bytes, of the buffer pointed to by pPrinterEnum.
  _Out_  LPDWORD pcbNeeded,
  _Out_  LPDWORD pcReturned
);

	DWORD dwSize,dwPrinters;
	::EnumPrinters(PRINTER_ENUM_LOCAL,NULL,5,NULL,0,&dwSize,&dwPrinters);
	BYTE* pBuffer=new BYTE[dwSize];
	::EnumPrinters(PRINTER_ENUM_LOCAL,NULL,5,pBuffer,dwSize,&dwSize,&dwPrinters);
	if(dwPrinters!=0)
	{
		PRINTER_INFO_5* pPrnInfo=(PRINTER_INFO_5*)pBuffer;
		for(UINT i=0;i<dwPrinters;i++)
		{
			m_listbox.AddString(pPrnInfo->pPrinterName); //m_listbox : Listbox控件变量
                        pPrnInfo++;
		}
	}
    delete[] pBuffer;
