PARALLEL HIGH
SPEED=YES
YES
NO
Select the speed at which data is transmitted to
the printer.
YES
: The printer accepts faster parallel
communications used for connections with
newer computers.
NO
: The printer accepts slower parallel
communications used for connections with older
computers.
PARALLEL ADV
FUNCTIONS=ON
ON
OFF
Turn the bidirectional parallel communication on
or off. The default is set for a bidirectional
parallel port (IEEE-1284).
This setting allows the printer to send status
readback messages to the computer. (Turning
on the parallel advanced functions might slow
language switching.)
SERIAL
PACING=DTR/DSR
DTR/DSR
XON/XOFF
Select the type of pacing used. Pacing, or
“handshaking” allows the printer to tell the
computer when to send information. The printer
uses XON/XOFF and DTR/DSR signal protocols
rather than ETX/ACK protocol.
DTR/DSR
: Select this value if your computer
requires hardware flow control (most personal
computers do).
XON/XOFF
: Select this value if your computer
requires software flow control (a UNIX
workstation, for example). The
SERIAL
ROBUST XON
item appears (see below).
