1 INTRODUCTION

The Print Server is a compact wireless print server which connects
to your network through an access point under the infrastructure
mode or can be used in ad-hoc mode for direct communication
between PC/Notebook and print server anywhere you wish to
locate wireless printer services. It manages the flow of print files
from your workstations or file servers to its connected printers,
delivering print jobs to high-performance printers much faster
than a file server or a PC acting as a print server can.

Print Server Features

The Print Server improve network printing services in three ways:
♦ The Print Server picks up the workload of managing print file

traffic to its connected printers. This provides workload relief to
your file servers, and allows the file servers' full capacity to be
used for file access or other direct services to network users. On
peer-to-peer networks, workstations can print directly to the
Print Server without increasing the load of another workstation
or server.

Introduction 1

♦ The Print Server's parallel printer ports are IEEE 1284

compliant high-speed b-directional ports, which can transmit to
high-speed laser printers much faster than a PC's parallel
printer port. High-speed laser printers connected to the Print
Server's parallel ports can be operated at their full capacity.

♦ Because the Print Server is very portable and inexpensive

compared to a PC-based print server, and because the Print
Server connects to your file servers through the network,
printers can be deployed to locations of maximum convenience
to users.

The Print Server offers extraordinary flexibility, operating with all
major network operating systems and protocols:

♦ IPX/SPX
Novell NetWare 3.x, 4.x, 5.x (Using either bindery emulation or

native NDS)

♦ TCP/IP
UNIX lpr/lpd (HP-UX, SunOS, Solaris, SCO, UnixWare, IBM

AIX)

Windows NT, Windows 2000/98/95/Me
♦ NetBEUI
Windows NT, Windows 2000/98/95/Me, Windows for

Workgroups, Microsoft LAN Manager, IBM LAN Server

♦ AppleTalk
MacOS EtherTalk
Windows-based setup and administration software, PS Admin, is

supplied with the Print Server, making configuration and
management quick and easy. The Print Server also supports

configuration and management via the telnet protocol for
networks without Windows-compatible machines.

External Features

This section describes the externally visible features of the Print
Server.

Port Connectors

The Print Server’s three printer ports are located on its rear panel.
Three identical parallel ports are labeled LPT1, LPT2 and LPT3.
These printer ports are independently configurable using the PS

Admin program or the print server’s telnet interface. (See the PS
Admin User’s Guide for information about configuring the print

server’s ports.)

are 2 types of settings, 802.11 ad-hoc mode and Proprietary ad-hoc
mode where there is direct communication between PC/Notebook and
print server.

Introduction 3

Under infrastructure mode there are 2 types of settings, Cfg ESS-ID
mode and Any ESS-ID mode where communication between
PC/Notebook and print server is through the Access Point acting as a
bridge between wired and wireless network.

Cfg ESS-ID (Configured ESS-ID)

• Connect to Access Point with ESS-ID

• Default ESS-ID is ‘default’

Any ESS-ID

• Connect to Access Point with any ESS-ID close to the unit

Reset Button

Reset will be initiated when the reset button is pressed once and
the LPT1, LPT2 & LPT3 begins to flash.

Factory Reset will be initiated when the reset button is pressed for
three seconds or when the LPT1, LPT2 & LPT3 begins to light up.
Release the reset button and LPT1, LPT2 & LPT3 will begin to
flash indicating the print server is changing to factory reset. When
factory reset is completed the print server will be set to default on
channel 11 and EES-ID is set as ‘default’.

DC Power Connector

The DC power input connector is located on the Print Server’s rear
panel and is labeled DC 5V/2.4A.

LED Indicators

The front panel of the Print Server features several LED indicators:

Front Panel LED Indicators

♦ Power

◊ Steady green confirms that the Print Server is powered

on.

♦ Link/Act

◊ In infrastructure mode steady or flashing green confirms the

Print Server has a good connection to the Access Point.

◊ In ad-hoc mode steady or flashing green confirms connection

to other PC/Notebook.

◊ The indicator blinks off briefly to indicate that the Print

Server is receiving/transceiving from/to the wireless network.

♦ Wireless Quality

◊ These LED indicators light is to show that the Print Server

has wireless quality connections to the network in either ad­hoc or infrastructure mode.

◊ The first indicator lights up only shows poor wireless quality

connection.

◊ The first & second indicator lights up simultaneously shows

moderate wireless quality connection.

Introduction 5

◊ All three indicator lights up simultaneously shows high

wireless quality connection.

♦ LPT1, LPT2, LPT3

◊ These LED indicators light to show that the Print Server is

transferring print data through the appropriate parallel port.

These three indicators are also used by the print server’s

power-on self test (POST) to indicate any hardware failures.

2 UNPACKING AND

INSTALLATION

This chapter explains how to install your Print Server and connect
it to the network. It also describes the print server self test
indications.

Unpacking and Inspecting the Print
Server

Carefully remove all items from the package. In addition to this
Hardware User’s Guide, be certain that you have:

♦ One 3 Parallel Port wireless print server
♦ One AC power adapter suitable for your country’s electric

power

♦ One Wireless Print Server Installation CD-ROM
♦ One Quick Installation Guide

Unpacking and Installation 7

If any item is missing, or if you find any damage or mismatch,
promptly contact your dealer for assistance.

Installing the Print Server

WARNING: Configuration problems may result if the Print

Server is powered up without first establishing
its network connection. Follow this procedure
to avoid complications at the configuration
stage.

1. Confirm proper operation of each of the printers to be
connected to the Print Server.

2. When you have confirmed proper operation of each printer,
switch its power off.

3. Confirm that your wireless network is operating normally.

4. (a) Ad-Hoc Mode

u Before initiating set-up procedure for the print server make sure

your wireless PCMCIA card on your PC/Notebook is set to
channel 11 with ESS-ID set as ‘default’ in ad-hoc mode.

u Make sure the DIP switch on the print server is positioned in the

ad-hoc mode.

u Press the Reset button on the print server for three seconds until

the LPT begins to light up initiating the factory reset.

u When factory reset is completed the print server will be set to

default on channel 11 and ESS-ID is set as ‘default’.

Note 1:

8 Unpacking and Installation

3 Parallel Port Multiprotocol Wireless Print Server User’s Guide

When changes are made on the print server’s wireless channel and ESS-ID it
must correspond to the PC/Notebook channel and ESS-ID for direct wireless
communication.

Note 2:

The print server’s ad-hoc mode supports two modes (802.11 ad-hoc mode
and proprietary ad-hoc mode). You can position the DIP switch on the print
server to the mode you want to operate. Which option of the ad-hoc mode is
required depends on the operation of your print server. It depends on which
ad-hoc mode is supported by your wireless card driver on the PC/Notebook.
Some driver supports both modes, however, some driver support only one of
the modes. The names of each ad-hoc mode may not be consistent between
each wireless card vendor therefore you may need to try each of the ad-hoc
mode (80.211 mode and proprietary mode) and select the mode that can
communicate with each other.

4. (b) Infrastructure Mode

u Before initiating set-up procedure for the print server make sure

your wireless PCMCIA card on your PC/Notebook is set to
channel 11 with ESS-ID set as ‘default’ in ad-hoc mode.

u Make sure the DIP switch on the print server is positioned in the

ad-hoc mode.

u Press the Reset button on the print server for three seconds until

the LPT begins to light up initiating the factory reset.

u When factory reset is completed the print server will be set to

default on channel 11 and ESS-ID is set as ‘default’.

u Start-up PS Admin to modify the print server’s ESS-ID to match

with the Access Point’s ESS-ID and this will link the print server
to the Access Point. The ESS-ID uses “default” as the factory
setting.

u From the DIP switch on the print server alter to infrastructure

mode and the print server will reset.

Unpacking and Installation 9

Note 1:

Please make sure to change your PC/Notebook to infrastructure mode. The
ESS-ID on PC/Notebook and print server must match with the Access Point’s
ESS-ID.

Note 2:

The print server supports two infrastructure operations (‘Cfg ESS-ID mode
and ‘Any ESS-ID’ mode).

‘Cfg ESS-ID’ mode: The print server will connect to the access point that
have the same ESS-ID with the print server’s configured ESS-ID.

‘Any ESS-ID’ mode: The print server will connect to any access point that
print server finds first, however, the ESS-ID may not be the same with each
other. This is an easier way to connect to the access point if you only have
one access point, but be careful, it may connect to your neighbor’s access
point.

5. While each printer is powered off, install a printer cable to
connect its parallel port to the printer port of the Print
Server.

6. Switch on each connected printer.

7. Plug the AC power adapter’s DC output plug into the DC 5V

power socket on the rear panel of the Print Server.

8. Plug the power adapter into an electric service outlet. This
will supply power to the Print Server, as it has no external
power switch. The Power LED on the Print Server’s front
panel should light steady green, and the Print Server’s self­test will proceed.

10 Unpacking and Installation

3 Parallel Port Multiprotocol Wireless Print Server User’s Guide

Power On Self-Test

When the Print Server is powered on, it automatically performs a
self-test on each of its major components. The final result of the
self-test is signaled by the state of the LPT1, LPT2, and LPT3 LED
indicators following the self-test. Preliminary to the actual
component tests, the three LED indicators are tested to confirm
their steady and flashing operation.

Immediately after power-up, all of the LED’s should show steady
green for several seconds. Then the LPT1, LPT2, and LPT3 LEDs
should flash on simultaneously three times. Irregularity of any of
the three LEDs during these LED tests may mean there is a
problem with the LEDs themselves. Contact your dealer for
correction of any LED problems before proceeding.

The actual component tests immediately follow the LED tests. A
normal (no fault) result is signaled by a series of three cycles of
sequential flashing of the three LEDs, followed by a quiescent state
with all three LEDs dark.

If the self-test routine traps any component error, then following
the LED tests the self-test will halt and the LED’s will
continuously signal the error according to the following table. In
the event of any such error signal, contact your dealer for
correction of the faulty unit.
