LoadLibrary() fails to 16-bit DLL or Windows driver

I had a 16-bit application which uses LoadLibrary() to load a printer driver(HPPCL5MS.drv) and it worked fine. I converted the application to 32-bit. The application fails to load HPPCL5MS.DRV using LoadLibrary() in Win95. GetLastEror() return error 31. Can someone help me on this?

Hare is part of the code:

HINSTANCE hPrintDriver;
hPrintDriver = LoadLibrary("c:\\windows\\system\\hppcl5ms.drv");

if (hPrintDriver == NULL)
{
   dwLastError = GetLastError();
   ASSERT(FALSE);//ERROR OCCURRED.
   return;
}
//
//  Get a DEVMODE structure
//
LPFNDEVMODE lpfnDevMode = (LPFNDEVMODE)GetProcAddress(hPrintDriver, "ExtDeviceMode");
