10	/ACK	Output	Parallel	Data processing end signal
11	BUSY	Output	Parallel	Receive data not ready signal
12	PE	Output	Para/Ser.	No paper signal
13	SLCT	Output	Parallel	Connection select signal
14	Not fixed			*	For extension
15	/ERROR	Output	Para/Ser.	Control stop signal
16	/INIT	Input	Para/Ser.	Initialize signal
17	Not fixed			*	For extension
18,19	GND	-	Para/Ser.	Ground for signal
20	/LF	Input	Para/Ser.	Paper feed signal
21	TXD	Output	Serial	Transmit data
22	RXD	Input	Serial	Receive data
