Chapter 7 Setting Up the Printer
ENQ/ACK
In this protocol, communication is controlled by the control
characters ENQ (ASCII 05 dec.) and ACK (ASCII 06 dec.) being
transmitted on the same line as the data. The sending unit transmits
ENQ at regular intervals. If the response ACK is not received,
the transmission is held up awaiting an ACK character from the
receiving unit. By default, ENQ/ACK is disabled.
XON/XOFF
In this protocol, communication is controlled by the control
characters XON (ASCII 17 dec.) and XOFF (ASCII 19 dec.) being
transmitted on the same line as the data. XON/XOFF can be
enabled/disabled separately for data received from the host by the
printer (printer sends XON/XOFF) and for data transmitted to the
host from the printer (host sends XON/XOFF).
XOFF is sent from the printer when its receive buffer is lled
to 75% and the transmission from the host is held, waiting for
an XON character. When enough data have been processed so
the receive buffer is lled only to 50%, the printer sends an
XON character and the host resumes transmitting data. The same
principles apply to XON/XOFF sent by the host, even if the
percentage gure may differ.
By default, XON/XOFF is disabled for data both ways.
New Line
Selects the character(s) transmitted from the printer to specify the
switching to a new line. There are three options:
CR/LF ASCII 13 dec. + ASCII 10 dec. (default)
LF ASCII 10 dec.
CR ASCII 13 dec.
Receive Buffer
The receive buffer stores input data received on the serial channel
before processing. Default size is 300 bytes.
Transmit Buffer
The transmit buffer stores output data to be transmitted on the serial
channel before transmission. Default size is 300 bytes.
