NOTES:

When the remaining space in the receive buffer is 16 bytes, the printer becomes buffer-full. This status continues until the space in the receive buffer increases to 32 bytes.

The printer ignores the data received when the remaining space in the receive buffer is 0 bytes.

On-line/Off-line switching

The printer does not have an on-line/off-line button. The printer goes off-line under the following conditions:

Between the time when the power is turned on (including reset using the interface) and when the printer is ready to receive data.

During the self-test.

During paper feeding using the PAPER FEED button.

Between the time when the printer stops printing due to a paper-end and when the on-line recovery wait time finishes after loading paper (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 feature set enabled due to paper shortage by ESC c 4).

Handshaking:	nAck and Busy signals
Signal levels:	TTL compatible
Connector:	57RE-40360-830B (DDK) or equivalent (IEEE 1284 Type B)
Reverse communication (Printer Host):		Nibble or Byte Mode

Reverse 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.

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 unists of four bits (Nibble). In the Byte Mode, data transmissions are proceeded by making the eight-bit data lines bidirectional.

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