An example of an OpenDriver call is as follows:

hDRVR = OpenDriver(“61SCAN.DRV”, (LPCSTR)NULL, (LPARAM)NULL);

The scanner is powered on, and scanner data is delivered to the application with

the input focus as WM_CHAR messages. These messages are distinguishable

from standard" WM_CHAR messages in that the virtual key code in wParam is

the ASCII value of a scanned character and lParam is sent as 0x00000000 (in

particular, the OEM nibble (bits 16ć23) that contains the OEM scan code of 0).
An example of an CloseDriver call is as follows:

CloseDriver(hDRVR, (LPARAM)NULL, (LPARAM)NULL);

This turns the scanner off.

NOTE:

See the Borland C++ help for OpenDriver / CloseDriver. See also Windows 3.1 SDK for
additional information.

NPCP Printing for Windows: NOR4800.DRV,
UNIDRV.DLL

NPCP printing support under Windows consists of DOS device driver

NORNPCP.SYS, a DOS TSR NORPAPI.EXE, and Windows printer driver

NOR4800.DRV/UNIDRV.DLL. These device drivers work together to provide

transparent NPCP printing. Applications use the standard Windows printing

API (StartDoc(), EndDoc(), etc.) to print to a printer set up for LPT1.DOS output.
