Determine 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.
