Initialization

The printer can be initialized (returned to a fixed set of conditions) in these ways:

Hardware ∗ The printer is turned on.

initialization ∗ The printer receives an INIT signal from the parallel interface.

Software ∗ Software sends an ESC @ (initialize the printer)

initialization command.

Hardware initialization

When the printer is turned on, the printer mechanism is initialized and the input data buffer and print buffer are cleared. Printer settings are returned to their default values. However, the printer mechanism is not initialized if the printer is turned on within ten seconds after turning it off. In this case, the printer caps the print head, and ejects any paper in the paper path.

Software initialization

This clears the print buffer and returns printer settings to their default values. However, it does not initialize the printer mechanism or clear the data buffer.

Interface

Your printer is equipped with an 8-bit parallel interface and a serial interface.

Signal level:	TTL compatible
Connector:	57-30360 Amphenol connector or
	equivalent
Reverse channel
Transmission mode:	IEEE-1284 Nibble mode
Adaptable connector:	57-30360 Amphenol connector or
	equivalent
Synchronization:	Refer to the IEEE-1284
	specification
Handshaking:	Refer to the IEEE-1284
	specification
Signal level:	IEEE-1284 Level 1 device

Data transmission timing: Refer to the IEEE-1284 specificationSerial interface

The printer’s built-in serial interface is based on the RS-423 standard. This interface has the following characteristics:

Standard: Based on RS-423

Synchronization: Synchronous
