(13) Transmission Control : XON/XOFF (DC1/DC3) Protocol
READY/BUSY (DTR) Protocol
XON/XOFF (DC1/DC3) Protocol + READY/BUSY (DTR)
Protocol
RTS Protocol
 XON/XOFF (DC1/DC3) Protocol
 When initialized after power on, this printer becomes ready to receive data and sends an
XON code (11H). (Transmission or non-transmission of the XON code is selectable by
means of the parameter setting.)
 The printer sends an XOFF code (13H) when the blank positions in the receive buffer
become 1K bytes or less.
 The printer sends an XON code (11H) when the blank positions in the receive buffer are
2K bytes or more.
 When there are no blank positions in the receive buffer, the printer discards data received
exceeding the receive buffer capacity, without storing it in the buffer. (After detecting the
XOFF code, the host computer must stop transmission before the printer receive buffer
becomes full.)
 The printer sends an XOFF code (13H) when the power is off. (Transmission or non-
transmission of the XOFF code is selectable by means of the parameter setting.)
 READY/BUSY (DTR) Protocol
 When initialized after power on, this printer becomes ready to receive data and turns the
DTR signal to “High” level (READY).
 The printer turns the DTR signal to “Low” level (BUSY) when the blank positions in the
receive buffer are 1K bytes or less.
 The printer turns the DTR signal to “High” level (READY) when the blank positions in the
receive buffer are 2K bytes or more.
 When there are no blank positions in the receive buffer, the printer discards data received
exceeding the receive buffer capacity, without storing it in the buffer. (After detecting the
BUSY signal, the host computer must stop transmission before the printer receive buffer
becomes full.)
 The RTS signal is always “High”.
