(3) Parallel I/F Signal List
(Note 1) The signal name in parentheses shows the one in Nibble mode.
(Note 2) The function in Compatible mode is only described.
(Note 3) This printer supports the Nibble mode defined in the IEEE Standard 1284-1994 issued by
the Institute of Electrical and Electronics Engineers, Inc. Using computers or cables that are not
compliant with this standard may cause unexpected behavior.
(4) Signal Level
• LOW
: 0V to +0.4V
• HIGH : +2.4V to 5.0V
Pin No.

nAck(PtrClk)
FROM PRINTER
Signal indicating completion of data reception.It is outputted
at the trailing edge of Busy signal.
11
Busy(PtrBusy)
FROM PRINTER
Signal indicating whether the printer is ready to receive data
or not. When the signal is at high level, the printer is not
ready to receive data.
12
Perror(AckDataReq)
FROM PRINTER
This signal becomes high level when there is no paper in the
feeder entrance.
13
Select(Xflag)
FROM PRINTER
Always at high level.
14
nAutoFd(HostBusy)
TO PRINTER
Used for bi-directional communication.
15

HILEVEL
FROM PRINTER
Pulled up to +5V through 3.3k
Ω
resistance inside the printer.
19-30 GND
–
Signal ground
31
nlnit(nlnit)
TO PRINTER
When the low level lasts for about 50 μs or longer, the printer
is initialized. This may be active even if the low level lasts
only for less than 50 μs. With the factory defaults, this signal
is ignored.
32
nFault(nDataAvail)
FROM PRINTER
This signal becomes low level when the printer is in alarm
state.
33
GND
–
Signal ground
34
