Honor DSR Off*
On
DSR is one of the handshaking signals for most serial interface cables. The
Honor DSR setting determines whether the printer accepts the incoming
print data. If
Honor DSR is Off , data received on pin 3 of serial interface is
seen as valid data. If
Honor DSR
is set
On
, only data received while the
DSR signal is in high condition is treated as valid data.
The serial interface uses DSR to determine if data arriving on pin 3 is sent
by the host computer or created by electrical noise in the serial cable. This
electrical noise can cause receive errors and create corrupted data that
causes stray characters to print.
Set
Honor DSR On
to prevent any stray characters from printing.
