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 that the printer cannot receive more data. Once the vacant area for data in the buffer recovers to 256 bytes, the printer outputs an XON code or sets the DTR flag to high (SPACE), indicating that the printer is again ready to receive data. Error handling An * character is printed if a parity error, framing error, or overrun 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. -4Signal Pin 1 Signal FG TXD RXD Direction Description - This line is connected to the printer chassis. OUT Transmits data. This pin transmits serial data from the printer to the computer. IN Received data. This pin transmits serial data from the computer to the printer. Technical Specifications A-13
