基本和串口一样
hPort1 = CreateFile("\\\\.\\LPT1 ",GENERIC_WRITE,NULL,NULL,OPEN_EXISTING,NULL,NULL);
    if (hPort1 == INVALID_HANDLE_VALUE)
    {
        AfxMessageBox("并口打开失败！");
        return FALSE;
    }
    DWORD dwRead;
    unsigned int command = 0xff;
    if(!WriteFile( hPort1,&tangjin,1,&dwRead,NULL))
    {
         AfxMessageBox("发送数据失败！");
    }
