Bidirectional interfaces
The formatter receives incoming data through its bidirectional interface
(IEEE 1284) or USB interface. The parallel interface or USB interface
both provide high-speed, two-way communication between the printer
and the host, letting the user change printer settings and monitor printer
status from the host computer.
Note
LJ 4100 only: The user can configure the HIGH SPEED item in the
Control Panel menu. The default setting,
YES, allows the I/O to run
at higher speeds supported by most newer computers. When set to
NO, the parallel interface runs at a slower mode that is compatible for
older computers. The user can also configure the
ADVANCED
FUNCTIONS
item. The default setting, ON, allows for two-way parallel
communications. The
OFF mode disables this advanced functionality.
The I/O is compatible with the bidirectional parallel interface standard.
