Introduction

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.

Installation
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.

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 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.

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 chapter of the
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

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 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-to­peer printing solutions, see the Lantronix Lantronix web site.

TCP/IP Configuration

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 win­dow, then select
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.

5. Cycle power on the server. EZWebCon will let you know whether the conÞgura­tion 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
4 - 3
TCP/IP Configuration
In order for the ARP command to work on at least one IP address deÞned other than its own. If the ARP table is empty, the command will return an error message. Type 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:
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

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:

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

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:
192.0.1.83 MPS_xxxxxx
2. Add the host print queue to the
mps_prt|Printer on LAB MPS:\
:rm=MPS_xxxxxx:\ :rp=MPS_xxxxxx_TEXT:\ :sd=/usr/spool/lpd/mps_prt:
/etc/printcap
Þle:
The punctuation shown is required, and no extra spaces should be added.

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 documenta­tion 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:
