Well, since this is the native api group, let's just drop the old DOS
functions.  (Untested. Most of this is cut-n-paste, but also edited to
remove extra tests and error recovery code. The DOS_ names are because
these were conversion functions for a DOS application)

  Compile this as a Win32 console program.

#include	<windows.h>

HANDLE _fastcall DOS_OPEN_WRITE(char *filename)
{ return = CreateFile(
	filename,
	GENERIC_WRITE,
	0,
	NULL,
	OPEN_ALWAYS,

FILE_ATTRIBUTE_NORMAL|FILE_FLAG_SEQUENTIAL_SCAN|FILE_FLAG_WRITE_THROUGH,
	NULL);
}

DWORD _fastcall DOS_WRITE(HANDLE h,BYTE*b,DWORD c)
{	DWORD	written = c;
	return = WriteFile(h,b,c,&written,NULL);
}
BOOL _fastcall DOS_FLUSH(HANDLE h)
{
	return = FlushFileBuffers(h);
}
int main(void)
{	char	message[] = "This is a test\r\n1234567890\r\n\f";

	printer_handle = DOS_OPEN_WRITE("LPT1");
	DOS_WRITE( printer_handle, message, sizeof(message)-1 );
	DOS_FLUSH( printer_handle);
	CloseHandle( printer_handle );
	printer_handle = INVALID_HANDLE_VALUE;
	return 0;
}
