Description
1
-STROBE
I
Strobe pulse. Input data is latched at falling edge of the signal.
2-9
DATA 1-8
I
Parallel input data to the printer. bit 0:LSB
10
-ACKNLG
O
This signal (negative pulse) indicates that the printer has
received data and is ready to accept next one.
11
BUSY
O
This signal’s high level means that the printer is not ready to
accept data.
12
PE
O
This signal’s hugh level means that the printer is in a state of
paper-out error.
13
SLCT
O
Always at high level when the printer in powered on.
14
-AFXT
I
Not used
31
-INIT
I
This signal’s negative pulse initializes printer.
32
-ERROR
O
This signal’s low level means the printer is in a state of error.

*
The I/O column indicates the direction of the signal as viewed from the printer.
The busy signal is active (HIGH) under the following conditions:
-During data reception(See Figure 1-6)
-When the input buffer is full
-When the-INIT input signal is active (low level)
-During the hardware initialization
-When the-ERROR or PE signal is active
- During the self-test mode
-During the default setting mode
The -ERROR signal is active(LOW) under the following conditions:
-When a paper-out error occurs
-When a no ink catridge error occurs
-When a fatal error occurs
The PE signal is active (HIGH) under the following conditions:
-When a paper-out error occurs
