Interface Specifications

Baud rate

300, 600, 1200, 2400, 4800, 9600, 19200, 38400 bits per second

Signal level

RS-232C:Conforms to EIA

Connector

D-sub 25pin connector

Handshaking

The printer’s serial interface can use DTR (Data Terminal Ready) signal levels and XON/XOFF communication protocols either separately or in combination. When the vacant area for data in the input buffer drops to 128 bytes, the printer outputs an XOFF code or sets the DTR signal level to low (MARK), indicating it cannot receive more data.

Once the vacant area for data in the buffer recovers to 256 bytes, the printer outputs the XON code or sets the DTR flag to high (SPACE), indicating it is again ready to receive data.

Error handling

A * character is printed if a parity error, framing error, or over run error is detected.

Serial interface pin assignments

The serial interface connector pin assignments and a description of the interface signals are shown in the table below. The direction of signals is given relative to the printer.
