Menu Options
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. When enabled, 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.
