Table 1-10. Signal and Connector Pin Assignments forParallel Interface

Pin No. Signal Name I/O* 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) indicatesthat 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 Alwaysat high level when the printerin 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.

35 +5 V — Pulled upto +5 V through 1.0 KΩresistor in the printer.

36 -SLIN In Not used.

17 CHASSIS —- Chassis ground

18 Logic H O Pulled up to +5V through 3.9 KΩresistor.

16,33

19-30 GND — Signal ground.

15,34 NC —- Notconnected.

* TheI/O columnindicates the direction of the signal as viewed from the printer.

Thebusy signal is active (HIGH) under the following condit ions:

-During data reception(See Figure 1-6)

-When the inputbuffer is full

-When the-INIT inputsignal is active (low level)

-During the hardware initialization

-When the-ERROR or PE signal is active

- Duringthe self-test mode

-During the default setting mode

The-ERROR signalis active(LOW) under the following conditions:

-When a paper-out error occurs

-When a no ink catridge error occurs

-When a fatal error occurs

ThePE signal is active (HIGH) under the following conditions:

-When a paper-out error occurs
