LOCAL AREA NETWORK (LAN) OPTIONAL INTERFACE
A Local Area Network (LAN) interface is a Plug-In Interface Module that can be
installed by the user. It requires a driver shipped with each printer that has the
interface installed. The driver that must be loaded on your PC and the PC must be
configured to run one of the supported network protocols using a 10/100BaseT LAN
connection. Details for loading the LAN driver are contained in the LAN Interface
Manual that is shipped with each printer with a LAN Optional interface installed.

BI-DIRECTIONAL COMMUNICATIONS

This is a two-way communications protocol between the host computer and the
printer, thus enabling the host to check printer status. When Bi-Com 4
communications is selected, there is no busy signal from the printer. The host must
request the complete status from the printer, including ready/busy. The host may
request status in two different ways.
ENQUIRE/ACK/NAK
In the Bi-Com 4 mode, the host transmits an ENQ (05 hexadecimal) to the printer
and the printer will respond with its status within five milliseconds. If printing, it will
respond upon finishing the current label, then resume printing. In order for this
protocol to work properly with an RS232 Optional Interface, pin 6 (DTR) and pin 5
(CTS) must be held high by the host. One way to ensure these pins are always in the
correct state is to tie pin 20 (DTR) to pin 6 (DSR) and pin 4 (RTS) to pin 5 (CTS) at
the printer end of the cable.
