	Centronics Parallel Pin Assignments
Pin	Signal	Direction	Description
1	Strobe	In	A low pulse greater than 1µs causes the
			printer to read one byte of data.
2	DATA0	In	Data Bit 0
3	DATA1	In	Data Bit 1
4	DATA2	In	Data Bit 2
5	DATA3	In	Data Bit 3
6	DATA4	In	Data Bit 4
7	DATA5	In	Data Bit 5
8	DATA6	In	Data Bit 6
9	DATA7	In	Data Bit 7
10	Acknlg	Out	The printer sends a low pulse to indicate
			that it has accepted a byte of data and
			is ready for more data.
11	Busy	Out	The printer sends a high logic level to
			indicate to the host that it cannot receive
			data due to data entry, a full buffer or
			error condition.
12	Paper Error	Out	The printer sends a high logic level to
			indicate to the host that it is out of paper.
13	On Line	Out	The printer sends a high logic level to
			indicate to the host that it is on line.
14, 15			Not Used
16	Sig Gnd
17	Chassis
	Gnd
18	HI	Out	The printer outputs a high logic level
			(+5V through a 2.2K ohm resistor) on this
			pin when it is turned on.
19-30	Sig Gnd	In
31	Reset/Input		A low pulse greater than 10µs sent by the
			host that resets the printer and clears the
			print buffer.
			NOTE: The printer may not work when
			this line is held low.
32	Error	Out	The printer sends a low logic level to the
			host to indicate that it is in an error state;
			self test failed or carriage position lost.
