Signal functions

Signal name	Function
/STB	Signal for sending data to printer.
	Steady-state value is High. Printer
	reads data until this signal becomes
	from Low to High.
DATA0 to	Input signal for receiving 8-bit data.
Data7	Logic 1 is High. DATA0 is
	LSB and DATA 7 is MSB.
/ACK	Signal indicating that printer has
	read data into device completely.
	This signal is output in response to
	/STB.
BUSY	Signal indicating that printer is
	unable to receive data. Printer is
	able to receive data when this signal
	is Low.
PE	Signal indicating Paper Out of
	printer. This signal is Low when
	paper is loaded and is High when
	paper is out.
SELECT	Signal indicating that printer is under
	online status. Printer is capable of
	receiving data when this signal is
	High.
/AUTFD	Signal used for bidirectional
	communication
GND	Ground
VCC	Signal indicating that the power of
	printer is on. This signal allows
	verifying ON/OFF status of power of
	printer and connection status of
	printer cable.
/INT	Signal for initializing printer. Steady-
	state value is High. Printer is
	initialized by Low.
/FAULT	Signal indicating that printer is faulty.
/SELIN	Signal used for bidirectional
	communication
