Item Options Explanation
PACING DTR/DSR*,
XON/XOFF
Pacing (or
handshaking
) allows the printer to tell the computer when to
send information. Select DTR/DSR if your computer requires hardware
flow control (most personal computers do). Select XON/XOFF if your
computer requires software flow control (for example, if you are using a
UNIX workstation).
BAUD RATE 9600*
300 to 57600
The baud rate tells the printer how fast information will be transferred
from the computer to the printer.
ROBUST XON ON*
OFF
Appears only when PACING is set to XON/XOFF. If it is set to ON, the printer
sends an XON when the printer is on line and when sufficient buffer
space has become available. If it is set to OFF, the printer sends one
XON when it can accept more data or when it is on line.
DTR POLARITY HI*
LO
Determines whether pin #8 is high or low when the printer is ready. When
it is set to HI, pin #8 is high when the printer is ready. When it is set to LO,
pin #8 is low when the printer is ready.
*Indicates factory default.
