I/O BUFFER SIZE=
100K
10K
and up This item appears only when
I/O BUFFER=ON
.
Specify the amount of memory for I/O buffering.
The maximum amount of memory available for
I/O buffering is determined by the amount of
memory installed in the printer, the languages
installed in the printer, and by other memory
allocations that must be made.
Press
[-Value +]
to change settings by
increments of 10 (up to 100 KB) or by
increments of 100 (above 100 KB).
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).
