NTRODUCTION

 

Congratulations on purchasing your  1-Port USB Print Server, the easiest and 
fastest way to deploy printers on your network. 

This  compact pocket-sized print server  can  connect your Ethernet network 
directly to your printer, wherever it is.    It manages the flow of print files from 
your workstation or file server 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. 

 

Package Contents 

Carefully remove all items from the package.    In addition to this 

Hardware 

User’s Guide

Service Features 

This 1-Port USB Print Server  can  improve network-printing services  of your 
network in three ways: 

 

It 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 this print server without increasing the load of another 
workstation or server. 

 

This  print server’s USB interface can transmit to a high-speed laser printer 
with USB port much faster than a PC's parallel port.  A high-speed laser 
printer can be driven at its full capacity. 

 

Because this 1-Port USB Print Server is very portable (pocket-sized) and 
inexpensive compared to a PC-based print server, and because  it connects

to your file servers through the network, the printer can be stationed at the 
location of maximum convenience to users. 

This 1-Port USB Print Server offers extraordinary flexibility, operating with all 
major network operating systems and protocols: 

 

TCP/IP

 

 

UNIX lpr/lpd (HP-UX, SunOS, Solaris, SCO, UnixWare, IBM AIX) 

 

Windows NT/2000/XP, Windows 95/98/Me 

 

NetWare 5.x NDPS LPR remote printing 

 

NetBEUI

 

 

Windows NT/2000/XP, Windows 95/98/Me, Windows for Workgroups, 
Microsoft LAN Manager, IBM LAN Server 

 

AppleTalk

 

 

MacOS EtherTalk 

Your  1-Port  USB  Print Server’s package includes 

PS Admin

,

 a Windows -

based setup and admin istration program, making configuration and 
management of your print servers quickly and eas ily in a Windows 
environment.    This print server also has a Telnet interface for  management 
communications.    If Windows is not available on the station you choose for 
print server administration, then all configuration and management commands 
may be issued to this print server, and all console messages and management 
report information will be returned, via Telnet.

Steady light confirms that the Print Server is powered 
on.

Steady light confirms that the print server has a good 
connection to your network. 

When it  blinks (briefly dark), the print server is 
receiving/ transmitting data from/to the network.

Description

 

DC Power 
Input 

The DC power input connector is located on the 
Print Server’s  rear panel and is labeled DC 5V.   
Please note that the power supply included in the 
package is correct for this  1-Port USB Print Server; 
s ubstitution of other equipment may void 
warranty. 

Reset Button 

1.)

 

Press and release this button to reset the print 
server. 

2.)

 

Press and hold this button for three seconds 
(the USB LED on the front panel lights up) 
and then release it, the print server will 
resume the factory default settings. 

USB Port 

The USB port allows you connecting the print 
server to a printer with USB connector. 

LAN 
Connector  

This LAN  connector (RJ-45) provides  the printer 
server with connection to the network through the 
Ethernet cabling. 

This printer port is configurable by commands in the 

PS Admin

 program, or by 

commands issued to the  print server via Telnet.  See the 

PS Admin User’s 

Guide

 for configuration procedures.  The print server also supports web 

configuration, which allows  users to configure settings through the web 
browser.  The print server’s default IP address settings are:

Default IP address – 192.168.0.1 

 

Subnet Mask – 255.255.255.0 

Please note that t he PC’s IP address must correspond with the print server’s 
IP address in the same segment for the two devices to communicate.

NSTALLATION

 

This chapter explains how to install your print server and connect it to the 
network.    It also describes the automatic power-on-self-test (POST). 

Installing the Print Server 

Follow these steps for a trouble -free start of print server operations with your 
1-Port USB Print Server.    Please take particular notice of the warning in step 
4:

 the network connection should be made before supplying power to the 

print server

.

 

1.

 

Confirm proper operation of the printer to be connected to the print server. 

2.

 

When you have confirmed proper operation of the  printer,  turn  off the 
power. 

3.

 

Confirm that your network is operating normally. 

4.

 

Connect the  print server to the network (through the RJ-45  connector  of 
the print server). 

WARNING: 

Configuration problems may result if the  print server  is 

powered up without fi rst establishing its network connection.  Please 
follow this procedure to avoid complications at the configuration stage. 

5.

 

While the printer is powered off, connect the print server  through the 
cable to the printer’s USB port. 

6.

 

Turn on the printer’s power.

- 11 - 

7.

 

Connect the  DC end  of the  AC Power adapter to the DC power input 
socket of the  print server and  the AC end to the wall outlet.    This will 
supply power to the print server, and the POST routines will proceed 
automatically. 

Note: 

This print server  is built with  a default  IP  setting.  To prevent 

from any conflict in your network, it is recommended to use the PS Admin 
program to change the IP setting when there is some other device’s IP 
address is the same as the print server’s default IP.   

 

Power-up and Self-Test 

Whenever the  print server is powered up, two kinds of testing procedures 
follow automatically.  The first procedure is just a programmed series of LED 
flashes, to confirm proper operation of the three LED indicators.  The second 
procedure comprises programmed tests of each of the  print server's major 
components. 

LED Test Series 

Immediately upon power-up, all three of the LED indicators will show steady 
green/amber for a few seconds.  Then the USB indicator will flash three times 
while the Power LED remains steady.  Irregularity of any of the LEDs during 
this LED test series indicates that there is a problem with the LEDs 
themselves.  Contact your dealer for correction of any LED problems before 
proceeding. 

Component Test Series 

The actual component tests immediately follow the LEDs test.  If any error 
condition is found during the component test series, then the test will halt 
with the USB LED continuously signaling the particular error according to the 
following table.

Administration" section, under the heading "Upgrading the Print Server's 
Internal Firmware"). 

In the event that any of the other listed error conditions is encountered on
