Hi,
    Does any one know how to install a printer driver in win95/nt? I means
after I install the printer driver, then I can see the new installed printer
in "Printer folder?"

    Can anyone tell me what wrong with the following code:

 DRIVER_INFO_2 di2;
 ZeroMemory(&di2, sizeof(DRIVER_INFO_2));
 di2.cVersion = 1000;
 di2.pName  = "TestPrinter";
 di2.pEnvironment= "Windows 95";
 di2.pDriverPath = "c:\\prt\\testprt.drv";
 di2.pDataFile = "c:\\prt\\testprt.drv";
 di2.pConfigFile = "c:\\prt\\testprt.drv";

 if (!AddPrinterDriver("", 2, (LPBYTE)&di2))
 {
  TRACE("Fail to add printer driver - %s\n",
   CUtil::GetLastErrorMsg(GetLastError()));
  return 1;
 }

 // add printer
 PRINTER_INFO_2 pi2;
 ZeroMemory(&pi2, sizeof(PRINTER_INFO_2));
 pi2.pPrinterName= "TestPrinter";
 pi2.pPortName = "FAX:";
 pi2.pDriverName = "TestPrinter";
 pi2.pPrintProcessor = "WinPrint";
 pi2.pDatatype = "RAW";
 HANDLE hPrinter = AddPrinter(szPrinterName, 2, (LPBYTE)&pi2);
 if (hPrinter==NULL)
 {
  TRACE("Fail to add printer - %s\n",
   CUtil::GetLastErrorMsg(GetLastError()));
  return 3;
 }
 ClosePrinter(hPrinter);
--------------------------------------------------------------

    The AddPrinter causes fault in spool32.exe

I'm not very good in device driver development, but i looked up
in my MSDN Library and i found some intresting things to think
about.

IMHO It would be wise to copy these files to the system
driver directory (You can obtain this path by calling
GetPrinterDriverDirectory - see MSDN Library) .

MSDN Library says that you should pass NULL if you want to install
a driver on a local machiene

MSDN Library says that you should pass NULL if you want to install
a printer on a local machiene (same as above). The first parameter
is not then name of your Printer, but a pointer to a server where your
driver should be installed. The name is provided by pPrinterName of
your PRINTER_INFO_2 structure.

If this was useful, please be so kind and give me
a short response.

if I pass the NULL instead of "", the AddPrinter won't cause a fault in
spool32, but instead the function return a error code means the printer
driver is unknown. But the first function AddPrinterDriver succeeds.
Anyway, thanks.

By examination of registry, the following code does job well

DRIVER_INFO_2 di2;
ZeroMemory(&di2, sizeof(DRIVER_INFO_2));
di2.cVersion = 1000;
di2.pName  = "TestPrinter";
di2.pEnvironment= "Windows 4.0";    // not Windows 95
di2.pDriverPath = "testprt.drv";
di2.pDataFile = "testprt.drv";
di2.pConfigFile = "testprt.drv";
if (!AddPrinterDriver(NULL, 2, (LPBYTE)&di2))
{
  TRACE("Fail to add printer driver - %s\n",
  CUtil::GetLastErrorMsg(GetLastError()));
  return 1;

// add printer
PRINTER_INFO_2 pi2;
ZeroMemory(&pi2, sizeof(PRINTER_INFO_2));
pi2.pPrinterName= "TestPrinter";
pi2.pPortName = "FAX:";
pi2.pDriverName = "TestPrinter";
pi2.pPrintProcessor = "WinPrint";
pi2.pDatatype = "RAW";
HANDLE hPrinter = AddPrinter(NULL, 2, (LPBYTE)&pi2);

if (hPrinter==NULL)
{
