Printer Interfaces
Transmitted Data — Serial data stream from the printer for transmitting
status and control information to the host. Subject to protocol selection.
Request To Send (RTS) — Control signal from the printer. Subject to
configuration.
Clear To Send (CTS) — Status signal to the printer indicating the host is
ready to receive data/status signals from the printer. This signal is ignored in
the printer.
Data Set Ready (DSR) — Status signal to the printer indicating the host is
in a ready condition. This signal is ignored in the printer.
Data Carrier Detect (DCD) — Status signal to the printer. The ON
condition is required for the printer to receive data. This signal is ignored in
the printer.
Reverse Channel (RC) — Control signal from the printer. Subject to
configuration.
Data Terminal Ready (DTR) — Control signal from the printer. Subject to
configuration.
RS-232 Serial Interface Protocols
You can select the following serial interface protocol parameters from the
control panel to meet host interface requirements.
X-ON/X-OFF — The printer controls the flow of communication from the
host by turning the transmission on and off.
In some situations, such as the buffer is full or the timing of signals is too
slow or too fast, the printer will tell the host to stop transmission by sending
an XOFF character. If the host continues to send data, the printer will send an
XOFF character after additional characters are received.
ACK/NAK — With ACK/NAK protocol selected, the printer responds as
described for ETX/ACK protocol except the printer monitors the received
data for parity error. If a parity error is detected, a NAK character is
transmitted to the host upon receipt of the ETX character. The host is
expected to repeat the data transmission.
ETX/ACK — End of Text / Acknowledge. The host controls the flow of
communication to the printer by sending a block of data and ending the block
