			feed one line after each line is printed.
		DENSEL	Floppy Drive Density Select – This signal indicates if a low (250/300kBps) or
			high (500/1kBps) data rate is selected.
	57	NC	Not Connected (Reserved)
	58	PD7	Parallel Port Data 7 – This signal (0 to 7) provides a parallel port data signal
			and is the printer data MSB.
	59	IRRX	IR Receive Data (HPSIR or ASKIR)
