Parity

When this option is set to None, parity checking is disabled. The parity bit, if used, provides a basic form of error detection. See your computer manual and software documentation for the proper setting.

Stop Bit

Use this option to set the number of stop bits for each character of information sent to the printer. Stop bits signal the end of a character.

XOn/XOff

Use this option to set the XOn/XOff communications protocol to 5 On, Off, or Robust. You can use XOn/XOff protocol in combination with the DTR option setting. If set to Robust, the printer sends an XOn signal every one second when the printer is available to receive data.

DTR

Use DTR (Data Terminal Ready) to turn the printer’s DTR communications protocol on or off. You can use DTR protocol in combination with the XOn/XOff option setting.

DSR

When DSR (Data Set Ready) is Off, the signal level is permanently set High, allowing the printer to send data to the computer. For most communications purposes, this option should be set to Off (Signal level High). When DSR is On, data is sent to the computer only when DSR is High.
