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.
