Maybe a bug introduced in the past, /lp is currently not a valid command line option:

notepad4/src/Notepad4.cpp

Lines 6011 to 6019 in 08020fe

	case L'L':
	if (chNext == L'F') {
	flagSetEOLMode = IDM_LINEENDINGS_LF - IDM_LINEENDINGS_CRLF + 1;
	state = CommandParseState_Consumed;
	} else if (chNext == L'0' || chNext == L'-' || chNext == L'O') {
	flagChangeNotify = TripleBoolean_False;
	state = CommandParseState_Consumed;
	}
	break;
