PRINTER CONFIGURATION
58
Online/Offline will reflect only the condition indicated and does not
reflect a buffer full condition. Busy/Not Busy will cause DTR to
indicate both the online/offline status and buffer full condition (see “Busy
Polarity” above).
XON/XOFF Handshaking XON/XOFF
Off
Possible Values: Off*, On
Enables or disables the transmission of the XON and XOFF characters
from the printer to the host to control data flow to the printer. XOFF will
be sent whenever the printer goes offline or the serial buffer is full. XON
will be sent when it is again ready to receive characters.
ETX/ACK Handshaking ETX/ACK
Off
Possible Values: Off*, On
Enables or disables the ACK response to receipt of the ETX character.
This handshake method is useful for conditions where there are long
transmission line delays such as telephone lines, which may be routed
through satellites. An ACK character will be returned to the host computer
after an ETX character is received and processed. ETX characters used
for handshaking cannot be part of an escape sequence.
RTS/CTS Handshaking
RTS/CTS
OFF
Possible Values: Power On/Off*
If your Host system requires or supports hardware handshaking for data
flow control, it may be useful to change this parameter to ON. This may
apply especially to older Host systems using Full-duplex communications.
