1 - Introduction

The Lantronix Micro Print Server (MPS) is a multiprotocol print server that provides

shared network access to printers for a variety of network protocols and operating

systems. The MPS supports the AppleTalk (EtherTalk), Microsoft LAN Manager, Local

Area Transport (LAT), IPX (NetWare), and TCP/IP protocols. The MPS can queue

multiple pending jobs and service those jobs in the order that they are received from the

hosts. The Centronics parallel port on the back of the MPS is compatible with the

Hewlett-Packard Bitronics interface, which allows bi-directional communication on the

parallel port.

There are three MPS models which are the same except for the Ethernet interface used.

The MPS1-T has an RJ45 port for 10BASE-T connections, the MPS1-2 has a BNC

connector for 10BASE-2 connections, and the MPS100 can auto-negotiate between

10BASE-T and 100BASE-T media connected to its RJ45 port. The features, installation

process, and conÞguration procedures are the same.

NOTE:

In this manual, all MPS models will be referred to as Òthe MPSÓ or

Òthe ServerÓ unless a distinction needs to be made between them.

2.1 Product Description

The front panel of the MPS has a Test button, LEDs, a power connector, and one of the

following Ethernet ports: a BNC connector for 10BASE-2 (MPS1-2), an RJ45 port for

10BASE-T (MPS1-T), or an RJ45 port for 10/100BASE-T (MPS100). The rear panel has a

Centronics connector.

The

LINK

LED is solid green when there is a valid Ethernet network connection. The

ACT

(Activity) LED ßashes green or red when the server is in use. The

100

(100 MBit)

LED (MPS100 only) is solid green when a 100BASE-T network is connected.

1. Connect the MPS Centronics connector directly to your printerÕs connector.

2a. For MPS1-T and MPS100 models, connect a twisted pair Ethernet cable to the

MPS RJ45 connector.

2b. For MPS1-2 models, connect a thin coaxial Ethernet cable to the MPS BNC

connector.

3. Attach one end of the power cable to the MPS; plug the other end into an

electrical outlet. Power will come on automatically.

NOTE:

The LINK LED indicates a good network connection. The ACT LED gives

information about what the MPS is doing; for example, when code is being

downloaded as the unit boots, the LED will blink green quickly.

Allow 45 seconds for the unit to fully boot. The LINK LED will be lit if there is a

valid connection to the network, and the ACT LED should blink.

4. Print a Test page by pressing the Test/Reset button.

NOTE:

If the Test page does not print, refer to Appendix B, Troubleshooting.

5. Install EZWebCon on your 32-bit Windows PC to conÞgure your Server. The

EZWebCon software is located on the CD-ROM. See EZWebCon ConÞguration on

page 3-2 for more information.

Getting Started

3 - 1

3 - Getting Started

It is important to consider the following points before logging into and conÞguring the

MPS:

¥ The MPS IP address must be conÞgured before any TCP/IP

functionality is available. (See

Setting the IP Address

on page 4-2.)

¥ There are two important passwords on the MPS: the privileged

password and the login password.

Changing any server, service, or port setting requires privileged user

status. The default privileged password is

system

The login password is required for remote console logins. The

default login password is

access

NOTE:

If you would like to change either the privileged or login password,

either use EZWebCon or refer to the Print Server Reference Manual

located on the CD-ROM.

Getting Started

3 - 2

3.1 EZWebCon Conﬁguration

The EZWebCon conÞguration software is the recommended way to conÞgure the MPS.

EZWebCon is a graphical user interface that guides Þrst time users through the initial

conÞguration process and allows experienced users to update and change any

conÞgurable parameters. There are two important things to note about EZWebCon:

¥ Your Server must have an IP address before EZWebCon can log into

it for conÞguration purposes. See

Setting the IP Address

on page 4-2

for instructions.

¥ EZWebCon requires a Java Virtual Machine (JVM) on the client.

Lantronix provides JVM installers for Solaris and 32-bit Windows

users, as well as source code and instructions for compiling it for use

on other systems.

The EZWebCon software is located on the distribution CD-ROM. All instructions for

installing EZWebCon are provided in the README Þle. For assistance once EZWebCon

is running, refer to the EZWebCon on-line help.

NOTE:

EZWebCon is also available from the Lantronix FTP and BBS servers.

See Appendix D for more information about logging into the FTP and

BBS servers.

Getting Started

3 - 3

3.2 Incoming Logins

Incoming logins made via EZWebCon can be used to conÞgure the server. Incoming LAT

and TCP/IP logins can also be used.

Incoming Telnet is enabled by default to allow TCP/IP connections. To change this

setting, use the

DeÞne Server Incoming

command described in the

Command Reference

chapter of the

Print Server Reference Manual

located on CD-ROM.

Incoming logins do not prompt for a login password; therefore, you may wish to disable

them. If it is undesirable to disable incoming logins, the Server can be conÞgured to

prompt for a password with the

DeÞne Server Incoming Password Enabled

command.

3.3 Services

With few exceptions, a

service

must be created before print queues can be conÞgured on

the MPS. A service is a resource accessible to network hosts. A Lantronix service is also

known as a

remote printer

name or

remote queue

name on many operating systems.

The following 3 default services are available once the Server has booted:

MPS_

xxxxxx

_TEXT Used for text print jobs

MPS_xxxxxx_PCL Used for binary print jobs, such as plotter or PCL Þles

MPS_xxxxxx_PS Used for PostScript print jobs

Getting Started

3 - 4

If you need to modify a default service, see the

Server ConÞguration

chapter of the

Server Reference Manual

located on the CD-ROM. Be sure to reboot after conÞguring

services so that the changes take effect.

TCP/IP Configuration

4 - TCP/IP Conﬁguration

The EZWebCon conÞguration software is the easiest way to conÞgure the MPS. The

following sections cover IP address conÞguration and print conÞguration methods for

TCP/IP hosts.

NOTE:

The Server needs an IP address before you can use EZWebCon. See

page 4-2 for instructions.

The MPS provides two major methods of printing via TCP/IP: Berkeley remote LPR and

RTEL host software.

Neither Windows for Workgroups nor Windows 95 support LPR directly; however, there

are third party solutions available. For more information about recommended peer-to-

peer printing solutions, see the Lantronix

Windows 95 FAQ

on the CD-ROM or the

Lantronix web site.

TCP/IP Configuration

4 - 2

4.1 Setting the IP Address

The MPS IP address must be conÞgured before any TCP/IP functionality is available.

To set the IP address, use one of the following methods: EZWebCon; a directed Ping

packet; a DHCP, BOOTP, or RARP reply; or commands entered at the command line

(Local>) interface.

4.1.1 Using EZWebCon

The MPS must have an IP address before you can log into it using EZWebCon. To assign

the IP address from EZWebCon:

1. Start EZWebCon. Instructions for installing, running, and using EZWebCon can be

found on the distribution CD-ROM.

2. Click on the Lantronix logo menu in the bottom left corner of the EZWebCon win-

dow, then select

Assign IP Address to Server

3. Fill in the following information:

A. The last three bytes of the MPSÕs hardware address. The hardware address

is printed on the bottom of the Server.

B. The desired IP address.

TCP/IP Configuration

4 - 3

C. The subnet, if you wish to use a subnet other than the default.

D. The IP address of the TFTP server you wish to use, if desired.

4. Click

5. Cycle power on the server. EZWebCon will let you know whether the conÞgura-

tion was successful.

4.1.2 Using a Directed Ping Packet

The ARP/ping method is available under UNIX, Windows 95, and Windows NT. If the

MPS has no IP address, it will set its address from the Þrst directed IP packet it receives.

NOTE:

The ARP/ping method only works during the first two minutes of

MPS operation. After two minutes, an alternate method must be used

or the MPS must be rebooted.

On a

UNIX

host, create an entry in the hostÕs ARP table and substitute the intended IP

address and the hardware address of the server, then ping the server. This process

typically requires superuser privileges.

# arp -s 192.0.1.228 00:80:a3:xx:xx:xx

% ping 192.0.1.228

TCP/IP Configuration

4 - 4

In order for the ARP command to work on

Windows

, the ARP table on the PC must have

at least one IP address deÞned other than its own. If the ARP table is empty, the

command will return an error message. Type

ARP -A

at the DOS command prompt to

verify that there is at least one entry in the ARP table.

If there is no other entry beside the local machine, ping another IP machine on your

network to build the ARP table. This has to be a host other than the machine that you're

working on. Once there is at least one entry in the ARP table, use the following

commands to ARP the IP address to the MPS and make the MPS acknowledge the IP

assignment.

NOTE:

There should be replies from the IP address if the ARP command

worked.

When the MPS receives the ping packet, it will notice that its IP address is not set and

will send out broadcasts to see if another node is using the speciÞed address. If no

duplicate is found, the server will use the IP address and will respond to the ping packet.

The MPS will not save the learned IP address permanently; this procedure is intended as

a temporary measure to enable EZWebCon to communicate with the server, or allow an

C:\ ARP -S 192.0.1.228 00-80-A3-XX-XX-XX

C:\ PING 192.0.1.228

administrator to Telnet into the MPS. Once logged in, the administrator can enter the

Change IPaddress

command to make the address permanent.

Any host wishing to access the MPS will have to be told the MPSÕs IP address. This is

typically conÞgured in the unix Þle

/etc/hosts

or via a nameserver. Refer to the hostÕs

documentation for additional information.

4.1.3 Using a DHCP, BOOTP, or RARP Reply

At boot time a host-based DHCP, BOOTP, or RARP server can respond to an MPS request

for an available IP address. For information about conÞguring the DHCP, BOOTP, or

RARP server, see your host documentation.

4.1.4 Using the Command Line Interface

1. Connect to the serial port (Port 1) using a terminal emulation program. The serial

settings should be 9600 baud, 8 bits, 1 stop bit, no parity.

2. Become the privileged user and enter the new IP address.

4.2 Notes About LPR

There are four important things to note about the LPR printing method:

1. Because of the way the LPR protocol is typically implemented on the host, the

processing options and banner page are sent after the job data itself.

The MPS

will print a banner page at the end of a job, and cannot support most of the LPR

options.

If it is necessary to have the banner page at the beginning of the printout,

install and use the RTEL software. If banners are not needed, they can be disabled.

2. The MPS cannot print multiple copies of the print job when using the Ò-#nÓ lpr

option.

3. If two print queues on the host refer to two services on the same MPS, they must

use separate spooling directories.

4. No special purpose input or output Þlters can be used when printing via LPR. If

this functionality is necessary, use the named pipe interface program in the RTEL

print queue conÞguration software.

4.4 LPR on UNIX Hosts

The Berkeley remote printing system is supported on many machines, and is simple to

conÞgure.

This section describes how to conÞgure LPR print queues on generic UNIX hosts such as

SUN hosts. There are slight variations in LPR conÞguration for AIX, HP, and SCO hosts,

as will be explained in the following sections.

1. Install a print queue on your host by adding the MPS name and IP address to the

/etc/hosts

Þle:

2. Add the host print queue to the

/etc/printcap

Þle:

The punctuation shown is required, and no extra spaces should be added.

192.0.1.83 MPS_xxxxxx

mps_prt|Printer on LAB MPS:\

:rm=MPS_xxxxxx:\

:rp=MPS_xxxxxx_TEXT:\

:sd=/usr/spool/lpd/mps_prt:

TCP/IP Configuration

4 - 16

This will create a host queue named

mps_prt

. The

parameter is the name of the

MPS in the host's address file, the

parameter is the name of the service as it exists

on the MPS, and the

parameter specifies the name of a directory used to hold

temporary spooling files.

3. Create a world-writable spooling directory using the

mkdir

command.

4. If desired, use the

option to allow unlimited size Þles to be printed and the

option to prevent header pages from being generated. See the host's documenta-

tion or man pages for more information on the format of the printcap Þle and how

to create the spool directory.

5. Print to the queue using normal lpr commands:

# mkdir /usr/spool/lpd/mps_prt

# chmod 777 /usr/spool/lpd/mps_prt

% lpr -Pmps_prt /etc/hosts

+ 70 hidden pages
