Serial Interface
The printer’s serial interface has the following characteristics:
Data format
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 256
bytes, the printer outputs an XOFF code or sets the DTR signal level to low
(MARK), indicating that it cannot receive more data.
Once the vacant area for data in the buffer recovers to 512 bytes, the printer
outputs the XON code or sets the DTR flag to high (SPACE), indicating that
it is again ready to receive data.
Error handling
An asterisk (*) character is printed if a parity error, framing error or overrun
error is detected.
Word length: 7 or 8 bits
Parity: None, odd or even
Stop bits: 1 or 2
Printer ready (handshaking)
protocol:
Enabled (XON/XOFF protocol set
to ON)
Use the SelecType mode to set the data format.
Baud rate (approximately
equal to bits/second):
300, 600, 1200, 2400, 4800, 9600,
19200, 38400, 57600
Signal level: RS-232C – conforms to EIA
Connector: D-sub 25-pin or 9-pin connector
(computer)/D-sub 25-pin (printer)
