32	—					Output	This signal goes low under the following
32	—		Fault			Output	This signal goes low under the following
							printer conditions:
							(1) Ofﬂine
							(2) Paper out
							(3) Cut-sheet feeder error
							(4) Other printer error

							Reverse data transfer phase:
				Data Available			Reverse data transfer phase:
							This signal is set low when the printer is
							ready to send data to the host. During
							the data transfer, it is used as data bit 0
							(LSB), then data bit 4.
							Reverse idle phase:
							This signal is used to indicate that data is
							available.

			(SG)

34	—	—				—	No connection

35	—	+5 VR				Output	Pulled up to +5 V through a 3.3 kΩ
							resistor

36	—					Input	Not used
36	—		SLCT-IN			Input	Not used

				1284 Active			This signal goes high to cause the printer
							to enter the reverse data transfer phase
							(nibble mode).
