C.1 Parallel Interface
C.1.1 Parallel Interface Communication Modes
The printer features fast data transmission with the parallel interface. The
parallel interface mode can be activated from the operator panel.
See Changing Parallel Interface Modes on page 1-40.
Use a parallel printer cable that complies with the IEEE1284 standard.
Nibble (high) [default]
High speed data communication is used in compliance with the IEEE1284
standard. Ordinarily, you should leave this setting unchanged.
Auto
The printer automatically changes its communication mode to the one the
host computer is currently using.
Normal
The printer uses the standard communication method prescribed for
Centronics interfaces.
High-speed
This mode enables faster data transmission between the printer and the
host computer.
(Select this mode if printing problems occur when the printer is connected
to a workstation.)
C.1.2 Interface Signals
The pins of the parallel interface connector carry the signals listed in the
table in Parallel Connector Pin Assignment on page C-3. Asterisks in
the table indicate signals that are active low. The table also indicates
whether each signal is incoming or outgoing with respect to the printer.
