Handshaking protocolDTR and X-on/X-off handshaking protocols can beperformed under either RS-232D or 20mA Current Looptransmission.X-on/X-off Protocol

• Transmit timing of X-on signalThe X-on signal is transmitted when the power is firstturned on, or when the vacant area in the buffer isgreater than

With the status flag set, and data reception prohibited,the vacant area of the buffer gradually increases as theprinter continues to print. When the v
