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.

The printer accepts faster parallel

communications used for connections with

newer computers.

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).
