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 Series1, One Char Enquiry is automatically
disabled.
The options are Disable (the factory default) and Enable.
Printer Status
•
Disable. Printer status ignored.
•
ENQ/STX (see Table 7).
•
ENQ (see Table 8).
When enabled, the printer will respond to an ENQ character by sending a
status byte to the host. The type of status byte is determined by a Front Panel
Menu selection. The selections allowed are ENQ/STX and ENQ. The ENQ is
removed from the data stream.
