Parity

Even
Odd
None*
Ignore

This setting lets you select the parity for serial input and output data frames. Refer to the

Technical Reference

for more information about parity.

Honor DSR

Off*
On

The Honor DSR setting determines whether the printer uses its data set ready (DSR) signal.
DSR is one of the handshaking signals for most serial interface cables. The serial interface
uses DSR to distinguish data sent by the computer from data created by electrical noise in the
serial cable. This electrical noise can cause stray characters to print. Set Honor DSR On to
prevent stray characters from printing.
