		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.
