•
138200, 172800, 230400, and 345600 baud rates are only displayed in the
Standard Serial menu. These settings do not appear in the Serial Option 1, Serial

Determines whether the printer uses the DSR Signal
Notes:
•
Off is the factory default setting.
•
DSR is a handshaking signal used by most serial cables. The serial port uses DSR
to distinguish data sent by the computer from data created by electrical noise in
the serial cable. The electrical noise can cause stray characters to print. Set this
to On to prevent stray characters from printing.
