Programatically installing printer driver
<![CDATA[
Question:
My application uses a custom print dirver. Is it possible to
silently install a print driver in Windows 3.1 or Windows 95 without
user intervention?
Answer:
The following example silently installs a print driver. You will
need to copy the print driver files to the Windows\System directory
and add the following entries to the Win.Ini file.
Notes:
In the follwong example:
DriverName = Name of the driver;
DRVFILE - Filename of the driver minus the extension
(unless it is not ".drv").
Example:
procedure TForm1.Button1Click(Sender: TObject);
var
s : array[0..64] of char;
begin
WriteProfileString('PrinterPorts',
'DriverName',
'DRVFILE,FILE:,15,45');
WriteProfileString('Devices',
'DriverName',
'DRVFILE,FILE:');
StrCopy(S, 'PrinterPorts');
SendMessage(HWND_BROADCAST, WM_WININICHANGE, 0, LongInt(@S));
StrCopy(S, 'Devices');
SendMessage(HWND_BROADCAST, WM_WININICHANGE, 0, LongInt(@S));
end;
