Pacing (Handshaking)
Pacing (or “handshaking”) is a type of communication between
the printer and the computer. This is an important item in the
printer because it allows the printer to tell the computer when to
send information. If the printer is unable to receive information,
for example, when the print buffer is full or when the printer is
out of paper, a signal is sent to the computer to stop sending
information. When the printer is able to resume receiving
information, it sends another signal to the computer to send more
data.
Pacing is set through the control panel’s Serial Menu. Two types
of handshaking are supported by your printer:
• Select DTR/DSR through the Serial Menu’s PACING item if the
computer requires hardware flow control (most personal
computers do). Through the Serial Menu’s DTR POLARITY item,
the DTR polarity can be set to High or Low. The default is DTR
POLARITY=HI
• Select XON/XOFF through the Serial Menu’s PACING item if the
computer requires software flow control (for example, if you
are using a UNIX workstation). Note that status readback
messages are not paced when XON/XOFF is selected. Through
the Serial Menu’s ROBUST XON item, Robust Xon can be set to
ON (the default) or OFF. Note that the ROBUST XON item only
appears under the Serial Menu if XON/XOFF was selected.
