Poll Character
This option is for the Series1 protocol. Whenever the printer receives this
character, it sends a response to the host indicating the current state of the
printer (see Series1 protocol). It may be configured from 0 through FF
hexadecimal.
Poll Response
This option is for the Series1 protocol. After receiving a poll character, the
printer will wait the poll response time in milliseconds before sending the
response. It may be configured from 0 through 30.
Idle Response
This option is for the Series1 protocol.
• Disable (default)
• Enable. The printer will send a response character every two seconds
while the number of valid bytes in the buffer is less than 75 percent of the
buffer size.
One Char Enquiry
The One Char Enquiry mode uses the Poll Character to detect a request from
the host and sends a response back to the host. This option also allows you to
turn on and off this feature.
The Poll Character is removed from the data stream. If the Data Protocol is
set to ETX/ACK, ACK/NAK, or Series 1, One Char Enquiry is automatically
disabled.
Framing Errors
Possible errors that can occur when the printer’s serial interface settings do
not match those of the host computer.
• Enable (default). If a framing error occurs, a fault message will display on
the control panel.
• Disable. If a framing error occurs, a fault message will not display on the
control panel.
