Printer Configuration 

Parity 

Parity 

None

Possible Values:  None*, Even, Odd 

This feature sets the parity checking requirements for the data bits in the serial character frame.  The value must 

match the setting used on the host system. 

XON/XOFF Handshaking 

XON/XOFF 

Off

Possible Values:  Off*, On 

This feature enables or disables the XON/XOFF (DC1/DC3) character handshaking method used to control data 

flow from the host system to the printer.  When enabled, an XOFF character will be sent by the printer 

whenever the printer’s input buffer is nearly full.  An XON character will be sent whenever the printer’s input 

buffer becomes nearly empty or if the control panel Setup Mode has been exited. 

ETX/ACK Handshaking 

ETX/ACK 

Off

Possible Values:  Off*, On 

This feature enables or disables the ETX/ACK character handshaking method used to control data flow from the 

host system to the printer.  When enabled, an ACK character will be sent by the printer after an ETX character 

has been received and processed out of the input buffer.  ETX characters used for handshaking cannot be part of 

an escape sequence. 

RTS/CTS Handshaking 

RTS/CTS 

On

Possible Values:  Off, On* 

This feature enables or disables the RTS/CTS hardware handshaking method used to control data flow from the 

host system to the printer.  When enabled, the printer will activate the RTS signal whenever the printer’s input 

buffer becomes nearly empty or when the printer’s control panel Setup Menus are active.  The RTS signal will 

be deasserted whenever the printer’s input buffer becomes nearly empty or Setup Mode has been exited. 

Likewise, the printer will not send data to the host system if the host has asserted the CTS signal.
