Honor Init
Purpose:
To determine whether the printer honors hardware initialization requests from the computer. The
computer requests initialization by activating the INIT signal on the parallel interface. Many personal
computers activate the INIT signal each time the computer is turned on and off.

Job Buffering
Purpose:
To specify whether the printer temporarily stores jobs on the hard disk before printing.

NPA Mode
Purpose:
To specify whether the printer performs the special processing required for bidirectional
communication, following the conventions defined in the Network Printing Alliance (NPA) Protocol.

Note:Changing this menu item automatically resets the printer.
Parallel Buffer
Purpose:
To configure the size of the parallel input buffer.

Parallel Mode 1
Purpose:
To control the pull-up resistors on the parallel port signals. This menu item is useful for personal
computers that have open collector outputs on the parallel port signals.

Parallel Mode 2
Purpose:
To determine whether the parallel port data is sampled on the leading or trailing edge of strobe.

Honor DSR
Purpose:
To determine whether the printer uses the Data Set Ready (DSR) signal. DSR is one of the
handshaking signals for most serial interface cables.
Va l u e s :
The serial interface uses DSR to distinguish data sent by the computer from data created by electrical
noise in the serial cable. This electrical noise can cause stray characters to print....
