This option is for the Series1 protocol.
Whenever the printer receives this charac-
ter, it sends a response to the host indicat-
ing the current state of the printer (see
Series1 protocol).
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.
This option is for the Series1 protocol.
• Disable (factory default).
• Enable. The printer sends a response
character every two seconds while the
number of valid bytes in the buffer is less
than 75 percent of the buffer size.
The One Char Enquiry mode uses the Poll
Character to detect a request from the host
and sends a response back to the host. .

when serial interface settings of the printer
do not match those of the host computer. If
enabled (factory default), a framing error

control panel. If disabled no fault message
will be displayed.
