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
the parallel advanced functions on 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).
SERIAL ROBUST
XON=ON
ON
OFF
This item appears only when
SERIAL
PACING=XON/XOFF
. Select the method for
generating XONs.
ON
:
The printer sends an XON when the printer
is online and when sufficient buffer space is
available. If the host does not receive data
within approximately one second, the printer
will transmit additional XONs at one second
intervals until the host receives data.
OFF
:
The printer sends one XON when it can
accept more data or when it is online. The
printer does not send XONs every second
while the printer is online and ready for more
data.
