IEEE 1284-B Nibble Mode signals

The following table briefly gives connector pin assignments in IEEE 1284 mode.

Pin	Direction	Signal	Description
1	To printer	HostClk	High in reverse data transfer phase

2	To printer	DATA BIT 1
3	To printer	DATA BIT 2
4	To printer	DATA BIT 3
5	To printer	DATA BIT 4
6	To printer	DATA BIT 5
7	To printer	DATA BIT 6
8	To printer	DATA BIT 7
9	To printer	DATA BIT 8

These signals are the 1st to the 8th bits of parallel data.

These signals are active high for a logical 1.

10	From printer	PtrClk	Set to low to qualify data on reverse channel

11	From printer	PtrBusy	Reverse channel: Data 3 and 7

12	From printer	AckDataReq	Reverse channel: Data 2 and 6

13	From printer	Xflag	Reverse channel: Data 1 and 5

14	To printer	Host Busy	Set to low to indicate that the host can
			receive data
			Set to high Host Acknowledge Receipt

15			Not used

16			0 volts. Logic ground

17			Chassis ground

18	From printer	Peripheral Logic Set to high to indicate the printer is ON
		High	and all signals are in valid state.
			- Max output current 50 mA

19-29			0 volts. Signal ground

30			0 volts. Signal ground

D-3
