2.1.2 IEEE 1284 Bidirectional Parallel Interface

2.1.2.1 Compatibility Mode

(Data Transmission from Host to Printer: Centronics compatible) 1) Outline

Compatibility mode supports the compatibility with Centronics parallel interface.

2)	Specifications
	Data transmission:	8-bit Parallel
	Synchronization:	Externally supplied nStrobe signals
	Handshaking:	nAck and Busy signals
	Signal levels:	TTL compatible
	Connector:	ADS-B36BLFDR176 (Honda) or equivalent (IEEE 1284 Type B)
3)	Switching between online and offline

The printer is not equipped with any online/offline switch. The printer is placed into offline status in either of the followings:

1)When the power is turned on or until the printer becomes ready for data transmission after it is initialized by the reset signal (nInit) from the interface.

2)During the self-test.

3)When the cover is open.

4)During paper feeding using the paper feed button.

5)When the printer stops printing due to a paper-end (in cases when empty paper supply is detected by either the paper roll end detector or the paper roll near-end detector with a printing halt due to paper shortage enabled by ESC c 4).

6)During macro executing standby status.

7)When a temporary abnormality occurs in the power supply voltage.

8)When an error has occurred.

2.1.2.2Reverse Mode (Data Transmission from Printer to Host)

The STATUS data transmission from the printer to the host is proceeded in the Nibble or Byte mode.

•Description

This mode allows data transmission from the asynchronous printer under the control of the host. Data transmissions in the Nibble Mode are made via the existing control lines in units of four bits (Nibble). In the Byte Mode, data transmissions are proceeded by making the eight-bits data lines bidirectional.

The both modes fail to be proceeded concurrently with the Compatibility Mode, thereby causing half duplex transmission.
