Signal definition:

Table 5.2 lists parallel interface signals and their functions.

					Table 5.2	Parallel interface signals
Connector	Return				Signal
pin	line pin	Compati mode				Direction	Description
number	number				Nibble mode
1	19	Busy				Output	Data cannot be received when this signal is high,
							e.g., if the buffer is full or an error occurs.
					Printer Busy		Reverse data transfer phase:
							Data bit 3, data bit 7, then forward path (host to
							printer) busy status
2	20	Select (SLCT)				Output	This signal goes high when the printer is selected
							(online), and goes low when the printer is deselected
							(offline).
					X Flag		Reverse data transfer phase:
							Data bit 1, then data bit 5
3	21					Output	• Pulse signal indicating data reception completed
			Acknowledge
				(ACK)			(or data reception enabled) status
							• Issued when the printer switches from offline to
							online
					Printer Clock		Reverse data transfer phase:
							This signal goes high when data being sent to the
							host is established.
							Reverse idle phase:
							This signal is set low then goes high to interrupt the
							host, indicating that data is available.
