Selecting the baud rate
You can select from the following baud rates: 600, 1200, 2400, 4800, 9600,
and 19200 bps (bits per second). To set the baud rate, see the bit-rate

Handshake timing
When the vacant area for data in the input buffer drops to 256 bytes, the
printer outputs an X-OFF code or sets the DTR flag to 1 (MARK) to
indicate that it cannot receive data. When the vacant area for data in the
buffer increases to 512 bytes, the printer outputs an X-ON code or sets the
DTR flag to 0 (SPACE) to indicate that it is ready to receive data.
Error handling
When the printer detects a parity error, it prints an asterisk (
✽
). The
printer ignores all other errors, including framing and overrun errors.
