1: Introduction
The Lantronix Micro Print Servers (MPS100, LPS1-T and LPS1-2 models) are multiprotocol print servers that provide shared network access to printers for a variety of
network protocols and operating systems. The MPS supports the TCP/IP, IPX
(NetWare), Local Area Transport (LAT), AppleTalk, and LAN Manager p rotocols. The
LPS supports TCP/IP, NetWare, and LAT. Both types of servers can queue multiple
pending jobs and service those jobs in the order in which they are received from hosts.
The MPS100 can auto-negotiate between 10BASE-T and 100BASE-T media connected
to its RJ45 port. The features, installation process, and configuration procedures are the
same. The LPS provides a twisted pair (10BASE-T) o r BNC (10 BASE-2) connector fo r
network connections.
Note: In this manual, all MPS and LPS servers will be referred to as “the
MPS” unless a distinction needs to be made between models.

2: Installation
This chapter describes the various MPS models and shows how to install them into a
basic network situation.
2.1 MPS/LPS Product Description
The front panel of the MPS100 has a Test button, 3 LEDs, a power connector, and an
RJ45 connector for 100BASE-T. The rear panel has a Centronics connector. The front

panel of the LPS has a Test button, 2 LED’s, a power connector, and a 10BASE-T
network connector for the LPS1-T or a 10BASE-2 BNC connector for the LPS1-2. The
rear panel also has a Centronics connector.
The LINK LED is solid green when there is a valid Ethernet network connection. The
ACT (Activity) LED flashes green or red when the MPS is in use. The 100 (100 MBit)
LED (MPS100 only) is solid green when a 100BASE-T network is connected.
The Test button serves two functions. When pressed briefly, it prints a test page. When
pressed for five seconds while pluggi ng in the power cable, it returns the MPS to its
factory default configuration.

To install the MPS, complete the following steps in order. Refer to the numbers in the figure
for help.
1 Connect the MPS Centronics connector directly to your printer’s connector.
2 Connect an Ethernet cable to your MPS’s RJ45 or 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.
4 Allow 45 seconds for the MPS to fully boot.
❍ It will run through a set of power-up diagnostics for approximately 12 seconds.
The 4 LEDs will show varying patterns corresponding to the test being run.
❍ It will try to obtain configuration information via DHCP, BOOTP, and RARP.
This step could last approximately 15 seconds if no hosts answer the requests.
The OK LED will blink approximately 3 times per second, and the NETWORK
LED will blink occasionally as network requests are transmitted.
❍ It will determine if the code in its Flash is valid. If so, it will load the code and
begin normal execution. If not, the MPS will have to download software. See
Appendix D for more information.

5 Allow 45 seconds for the unit to fully boot. The LINK LED will be lit if there is a
valid network connection. The ACT LED gives infor mation abo ut what the MPS i s
doing; for example, when code is being downloaded as the unit boots, the LED will
blink green quickly. If you have co nnected a 100BASE-T cable (MPS100 only), The
Link and 100MBit LEDs s hould both be solid green. If not, check your network con nection.
6 Print a Test page by pressing the Test/Reset button.
Note: If the Power LED does not li ght o r the Tes t page do es not print , refe r
to Appendix B.

3: Getting Started
It is important to consider the following points before logging into and configuring the
MPS:
◆ You must configure the MPS IP address before any TCP/IP functionality is
available. (See Setting the IP Address on page 4-1) You cannot use t he ThinWeb
Manager until you have configured an IP address.
◆ Changing any server, service, or port setting requires privileged user status. The
default privileged password is system.
◆ The login password is requi red f or r e mote con so le logins. The default lo gin pass-
word is access.
Note: If you would like to change either the privi leged or logi n pas sword,
either use EZWebCon or refer to the Print Server Reference Manual
located on the CD-ROM.
3.1 Configuration Methods
3.1.1 EZWebCon
The EZWebCon configuration software is the recommended way to configure the MPS.
EZWebCon’s graphical user interface guides first time users through the initial
configuration process and allows experienced users to update any configurable
parameters.
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 other systems.
The EZWebCon software is located on the distribution CD-ROM. All instructions for
installing EZWebCon are provided in the README file. For assistance once
EZWebCon is running, refer to the EZWebCon on-line help.
Note: EZWebCon is also available from the Lantronix website and FTP
3.1.2 Incoming Logins
server. See Appendix D for more info rmation.
You can log in via EZWebCon to configure the MPS. you can also use incoming LAT
and TCP/IP logins.
3-1
Services Getting Started
Incoming Telnet is only possible if your MPS has an IP address configured. Incoming
Telnet is enabled by default to allow TCP/IP connection s. To ch ange this setting, use the
Define Server Incoming command described in the Command Reference chapter of the
Print Server Reference Manual located on the CD-ROM.
Incoming logins do not prompt for a login password, so you may wish to disable them for
security reasons. If it i s undesirable to dis able incoming lo gins, the MPS can be confi gured
to prompt for a password with the Define Server Incoming Password Enabled command.
3.2 Services
With few exceptions, you must create a service before you can configure print queues 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 default services are available once the MPS100, LPS1-T, or LPS1-2 has
booted:
Table 3-1: Default Services
MPS100 LPS1-T & LPS1-2 Function
MPS_xxxxxx_TEXT LPS_xxxxxx_TEXT Used for text print
jobs
MPS_xxxxxx_PCL LPS_xxxxxx_PCL Used for binary
print jobs, such as
plotter or PCL
files
MPS_xxxxxx_PS LPS_xxxxxx_PS Used for Post-
Script print jobs
The default service names are based on the server name; therefor e the server nam e must be
no more than 13 characters. If you change the server name, the service names will change
as well. For example, changing the server name from MPS_xxxxxx to BIOLAB will
change the service names to BIOLAB_TEXTS1 and so on.
The default serial port services have the TCP/IP, NetWare, LAN Manager, and AppleTalk
protocols enabled. Parallel port services have TCP/IP, NetWare, and LAN Manager
enabled. LAT is disabled by default on all services provided by the MPS because many
network managers object to the frequent LAT service announcements. AppleTalk is
disabled on parallel port services because AppleTalk requires Bitronics mode, which is
disabled by default.
If you need to modify a default service, see the Server Configurat i on chapter of the Print
Server Reference Manual located on the CD-ROM.
3-2
4: TCP/IP Configuration
The EZWebCon configuration software is the easiest way to configure the MPS. The f ollowing sections cover IP address co nfiguration and print config uration metho ds for TCP/
IP hosts.
4.1 Setting the IP Address
The MPS IP address must be configured before any TCP/IP func tionality is available.
Use one of the following methods to set the IP address: EZWebCon; a directed Ping
packet; a BOOTP, DHCP, or RARP reply; or commands entered via the command line
interface.
4.1.1 Using EZWebCon
Use the following steps to assign an IP address using the EZWebCon Expert Shell.
1 From the Action menu, select Assign IP Address.
2 Enter or change the IP-related settings:
A For Ethernet Address, enter the number that appears on the bottom label of
your MPS.
B For IP Address, enter the desired IP address to use for this MPS.
C For Subnet Mask, change the valu es provide d only if you wish to u se a mask
other than the default. The default value should be correct in most cases.
D For Loadhost, en ter th e I P add ress of th e lo adho st where yo u intend to store
your operating code and SDK files (if used).
3 Click OK.
4 Reboot the MPS. EZWebCon will let you know whet her the configuration was
successful.
Note: If you have an older version of EZWebCon , refer to the Read me that
was included with it.
4.1.2 Using a Directed Ping Packet
The ARP/ping method is available under UNIX and Windows-based sys tems. If the MPS
has no IP address, it will set its address from the first directed IP packet it receives.
4-1
Setting the IP Address TCP/IP Configuration
On a UNIX host, create an entry in the host’s ARP table and substitute the intended IP ad-
dress and the hardware address of the MPS, then ping the MPS. This process typically requires superuser privileges.
Figure 4-1: ARP and Ping on UNIX
# arp -s 192.0.1.228 00-80-a3-xx-xx-xx
% ping 192.0.1.228
In order for the ARP command to work on Windows, the ARP table on the PC must have
at least one IP address defined 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.
Figure 4-2: ARP and Ping on Windows
C:\ ARP -S 192.0.1.228 00-80-A3-XX-XX-XX
C:\ PING 192.0.1.228
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 specified address. If no duplicate is
found, the MPS 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 MPS, or allow an 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 MPS’s IP address. This is typically configured in the unix file /etc/hosts or via a nameserver. Refer to the host’s documentation for additional information.
4-2
TCP/IP Configuration LPR Printing
4.1.3 Using a BOOTP, DHCP, or RARP Reply
At boot time a host-based DHCP, BOOTP, or RARP server can r espond to an MPS request
for an available IP address. For information about configuring 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 console terminal or a terminal emulation
program, and press Return. The serial port settings are 9600 baud , 8 bits , 1 stop bit,
no parity.
2 Become the privileged user.

4.2 LPR Printing
The MPS provides two major methods of printi ng via TCP/IP: Berkeley remote LPR and
RTEL host software.
Two parameters must be configured for LPR printing:
1 The IP address or host name of the MPS.
2 The remote output queue (the name of the service on the MPS).
In addition, there are a few important things to note about LPR printing:
◆ Windows for Workgroups, Windows 95, and Windows 98 do not support LPR di-
rectly; however, Lantronix has provided a peer-to-peer printing solution on the distribution CD-ROM.
◆ Because of the way the LPR protocol is typically implemented on the host, the pro-
cessing 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 beginn ing of th e printout, in stall and use
the RTEL software. If banners are not needed, they can be disabled.
4-3
LPR Printing TCP/IP Configuration
◆ The MPS cannot print multiple copies of the print job when using the “-#n” lpr op-
tion.
◆ If two print queues on the host refer to two services on the same MPS, they must use
separate spooling director i es.
◆ No special purpose input or output filters can be used when printing via LPR. If this
functionality is necessary, use the named pipe interface program in the RTEL print
queue configuration software.
4.2.1 LPR on Windows NT 3.5.1 (and later)
This section assumes that TCP/IP, Simple TCP/IP, and Microsoft TCP/IP printing have
been installed on the Windows NT host.
1 In the Control Panel, double-click the Printers icon.
2 Double-click the Add Printer icon.
3 In the window that appears, choose My computer and click Next.
4-4
TCP/IP Configuration LPR Printing
4 Select the Add Port button and click Next.
5 Select LPR Port.
Note: If LPR Port is not an option, open the Networ k Control P anel and add
“Microsoft TCP/IP Printing” to the List of services.
6 Enter the name or IP address of your MPS on the first line, and enter the name of
your MPS print service on the second line.

7 Select the manufacturer and printer type.
8 Enter the queue name.
9 If applicable, choose Shared and select the type of operating system that the printer
will be working with. (First confirm that the print queue is working. )
4-6
TCP/IP Configuration LPR Printing
10 Test the printer by choosing Yes and clicking Finish.
4.2.2 LPR on Windows 95/98
To enable LPR printing on Windows 95/98, you must download and install the LPR for
Windows 95/98 application from the Lantronix CD included with the product.
1 From the Distribution CD, install Lantronix LPR.
2 Follow the directions in the readme file to configure LPR on your PC.
4.2.3 LPR on UNIX Hosts
The Berkeley remote printing system is supported on many machines, and is simple to configure. This section describes how to configure LPR print queues on generic UNIX hosts
such as SUN hosts. There are slight variations in LPR configuration 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 file:
Figure 4-6: Adding /etc/hosts Entry
xxx.xxx.xxx.xxx MPS_xxxxxx
2 Add the host print queue to the /etc/printcap file. The punctuation shown in Figure
4-7 is required, and no extra spaces should be added.
