∗1 • The period from when the remaining space in the receive buffer drops to 16 bytes until
it increases to 32 bytes is called the “buffer full state.”
• Data received when the remaining space in the receive buffer is zero bytes is ignored.
2.1.1.4 XON/OFF transmission timing
When XON/OFF control is selected, the printer transmits XON or XOFF signals as follows.
Transmit timing depends on the setting of DIP switch 1-8

NOTES: • The XON code is <11>H and the XOFF code is <13>H.
• In case 3), XON is not transmitted when the receive buffer is full.
• In case 6), XOFF is not transmitted when the receive buffer is full.

• When connecting the printer to a DCE (DCE: Data Circuit Terminating Equipment), set the
handshaking so that the transmitted data can be received.
• Transmit data to the printer after turning on the power and initializing the printer.
