Printer Support The M208 is compatible with PC’s, UNIX systems, Macintosh computers, minis, and mainframes as long as at least one of the following is present: TCP/IP • an LPR client to interact with our Line Printer Daemon on the unit, • an RSH client (i.e. rsh, remsh, rcmd) to interact with our RSH Daemon, • the ability to print directly to a TCP port number on our unit; we have a TCP port number mapped to each I/O port on the unit by default (i.e.
Overview of Print Server Architecture This section will provide an overview of how the M208’s Print Server component works. To better understand this, it is important to understand I/O ports, destinations and models. I/O Ports The M208 has three I/O ports; one parallel and two serial ports. Printers can be attached to any or all of the three I/O ports.
Summary When you are doing a print setup, you must direct print jobs to a particular destination which is mapped to an I/O port to which the printer(s) is attached. The destination’s associated model is then used for any extra processing of the data, if required. Each I/O port has an internal queuing mechanism that automatically queues print jobs on a first-come, first-serve basis. For more information on I/O ports, destinations, and models, please see M208 INTERNAL ARCHITECTURE on page 89.
Overview of Print Server Installation This section will provide an overview of the basic steps required to install the M208 in the various supported environments: Unix, Novell (PSERVER and RPRINTER), NetBIOS over TCP/IP, and AppleTalk. Note Before installing the M208, it may be useful to look at Appendix A, Planning Your Print Setup on page 203 for advantages/disadvantages of various configuration options.
Basic Novell Configuration PSERVER Setup The following outlines the basic steps required to add a M208 to a Novell network using a PSERVER setup and applies to any Netware version. The M208 replaces a dedicated workstation running PSERVER.EXE or PSERVER.NLM so these are no longer needed. Once the unit is physically attached to the network, you need to: 1 Enter into a PCONSOLE session. PCONSOLE is used for the entire print setup. 2 Create a new queue. 3 Create a new print server.
last six digits of the Ethernet address as found on the bottom of the unit. 8 Inside this directory, create a file called CONFIG. 9 Enter the line: set rprinter add pservername printernumber destname where pservername is the existing PSERVER’s name, printernumber is the defined number for this printer in that PSERVER, and destname is a M208 destination (e.g. d1prn, d3com2, etc.). 10 Reboot the Print Server and wait about a minute for it to connect to the file server.
the name of one of the eight default destinations on the unit. (e.g. d1prn, d3com2, etc.) For more information on NetBIOS over TCP/IP configurations, please see CONFIGURING THE M208 FOR WINDOWS on page 79. Basic AppleTalk Configuration The following outlines the basic steps required to add a M208 to an AppleTalk network. Note An AppleTalk setup does not require any Print Server configuration; the network parameters are automatically configured for you once the M208 is booted on the network.
INSTALLING THE M208 ON THE NETWORK Overview The first step of your M208 setup is to attach it to the network. This section tells you how to do that and also covers the M208’s network interfaces. Preparing for Installation Before unpacking and installing the hardware, read the FCC Warning. FCC Warning This equipment generates, uses and can radiate radio frequency energy. If it is not installed and used as directed in this manual, interference to radio communications may result.
Site Requirements Environment Prepare to install the M208 in a clean, well-ventilated environment protected from extremes of temperature, humidity, mechanical shock, or vibration. Provide enough space at the front and back of the unit for cable connections.
Connecting the M208 to the Network To connect the M208 to the network: 1 Connect Data Terminal Equipment (DTE) and other hubs/backbone to the appropriate ports (10Base-T or AUI port). Please see Hub Installation on page 20 for further details. 1 Connect peripherals to the appropriate I/O ports. Please see Connecting Peripherals on page 17 for details on each of the M208’s I/O ports. 2 Unpack and plug in the power supply. The connector plugs into the back of the M208.
Please see list prn on page 100, set prn on page 112, and PRN Pinout on page 183. Serial Port Connections (COM1, COM2) Two 9-pin male DE-9P connectors with IBM PC AT compatible pinouts are provided for connection to printers using serial ports. Each of these ports have various parameters which control such things as: • parity selection, generation, and detection, • hardware flow control, • software flow control, • character description.
USING THE HUB Overview The M208 Workgroup Hub/Print Server includes a fully managable and intelligent eight port Ethernet hub. Hubs (or multi-port repeaters) are stable network devices that perform signal regeneration (including amplification, symmetry, and retiming), packet forwarding, and routing. When a hub is presented with a data signal, it automatically regenerates and transmits the data signal to all the other hub ports without any modification to the signal.
• full hub monitoring capabilities using the npsh command set, • remote network management via private MIBs: the M208’s private MIB file contains all the variables and traps required to manage the hub using an SNMP manager, Hub Installation You can use any of the network ports to connect the M208 to computers, to other hubs/backbone, or to other Data Terminal Equipment (DTE). Connectors The M208 has 9 network connectors: eight 10Base-T (RJ45) connectors, and one AUI connector.

ured on the unit. Configuring the M208 with an IP address There are a number of ways to configure the M208 with an IP address, either automatically with a shell script or manually.
To disable link integrity on a specific port, please follow the steps below: 1 Login to the M208 as a root user. 2 At the npsh prompt, type the following command: config hub [portnum] [-]li where portnum is the number between 1 and 8 of the port that you want to disable link integrity. Note This command is not applicable to port 9 which is the AUI port. Note If the port LED stays lit even when no device is attached, this indicates that link integrity has been turned off for that particular port.
If you are using the AUI port without an external transceiver, the SQE Test can be used to verify the integrity of the connection. To enable the SQE Test on port 9, please follow the steps below: 1 Login to the M208 as a root user.
Hub Monitoring Using npsh The command set npsh provides extensive information regarding the operation of the hub including both the general operational status of the hub as well as information specific to each port. This information is valuable for monitoring the operation of the hub and for troubleshooting your network. To monitor the operations of the hub as a whole, please follow the steps below: 1 Login to the M208 as a root or guest user.
26 Collisions Displays the number of occurrences where the port has activity on both its receive and transmit pairs. This is a normal event within a CSMA/CD network. Excessive collisions, however, may indicate an overloaded network or a wiring error. Data Rate Mismatches Displays the number of occurrences where the frequency or data rate of the incoming signal is different from the local transmit frequency. Enabled Displays whether the port is enabled.
Readable Frames Displays the number of valid frames received by the port. Readable Octets Displays the number of valid octets received by the port. Rx Polarity Reversed Displays whether the receive polarity has been automatically reversed on the port. This occurs when the receive pair is miswired. Runts Displays the number of instances where activity is detected with a duration greater than the ShortEventMaxTime but less than the minimum valid frame time.
SNMP Management Features The M208 includes a private Management Information Base (MIB) file that contains a number of variables and traps that can be used to configure, monitor and manage all aspects of the unit. The M208 supports both MIB II and private MIBs, allowing it to be a fully managed agent using a SNMP manager such as HP’s OpenView, Sun’s SunNet Manager, and Castle Rock’s, SNMPc. The MIB is included in a file called mplxmib.txt that can found on the host software disk.
• If you plug another hub into one of the RJ45 ports (Hub to Hub) and the LED does not turn on, try plugging it into port one and setting the selector switch to the straight-through position (||). If this works, either use port one or change to a crossed-over cable.
30 USING THE HUB: Troubleshooting the Hub
CONFIGURING THE M208 FOR TCP/IP Overview If you are setting the M208 in a TCP/IP environment, this chapter will help you with all aspects of the setup process. The provided host software is introduced and then steps are given for configuring the M208 for communications over the network and for printing. Since TCP/IP encompasses a wide variety of system types, the common ones are covered in detail to help you get printing in a TCP/IP environment.
Compiling Host Software Some compilation may be needed before adding print setups to your host unless you have SunOS 4.1.x, Solaris 2.x, or SCO Unix. Pre-compiled binaries are provided for these. npconfig can be used to do the compilation or you can try and compile each program independently. For the npconfig method, please: 1 Select Detailed Configuration Options . . . from the npconfig Main Menu. 2 Select Manage Host Software . . . from the Options Sub-Menu.
Table 1: npconfig/ezsetup Main Menu Option Description Configure New Unit Add a M208 to your network. This option provides for: IP name, IP address, hardware address, netmask, and for root and guest passwords. (ezsetup as well) Configure Host Setup Configure a print destination on the host including communication mechanism and processing options. (ezsetup as well) Detailed Configuration Options . . See Table 2: npconfig Detailed Configuration Options Sub-Menu.

M208 Configuration When the M208 is first installed on a TCP/IP network, you are unable to communicate with it since its network parameters are not initialized. During configuration, the following parameters are initialized and saved in EEPROM: • IP address (mandatory), • netmask or sub-netmask(mandatory), • root user password (recommended for security), • guest user password (recommended for security).
Computer-aided Configuration with ezsetup or npconfig Note If you choose computer-aided configuration, you must log on to your system as root or superuser and use the host software diskette or tape supplied with your M208. If the software is not provided, or you need a different medium, contact your vendor. To configure the M208 with the aid of a script, you must: 1 Insert the host software medium into the drive. 2 Login as root user. 3 cd to a directory with at least three megabytes of free space.
Manual Configuration Through the Network with ARP To manually configure the M208 using the network, go to a host terminal and do the following: 1 Log on to your system as root user. 2 Assign an IP address and IP name to the M208 in your host table (/etc/hosts, hosts nis map, or DNS name tables). 3 Find the Ethernet address for the M208 on the bottom of the unit. It must be entered as part of this procedure. 4 Use the arp command to add an entry in the host's arp able.
ifnum is the index to a particular Network Interface. ifnum will always be 1 for the M208 since there is only one network interface, Ethernet. Note 9 [Optional, but recommended] Configure root and guest user passwords with the following commands. set user passwd root newrootpasswd set user passwd guest newguestpasswd 10 Save these configurations to EEPROM. Enter: save 11 Verify the IP address and netmask. Enter: list stored tcpip These are now stored in EEPROM.
3 Reboot the M208. After the STAT LED flashes regularly, wait another ten seconds to allow the RARP process to complete. 4 Test the new IP address by trying a ping with the new IP name: ping ipname 5 [Optional, but recommended] At this point, set up the user passwords. Please see set user on page 117. If no response is given by the M208, the RARP process probably failed. Reboot the unit and try one of the other methods mentioned in this section.
Manual Configuration Through the COM Port A terminal, PC, or laptop can be connected to one of the M208’s COM ports for configuration purposes. A straight-through serial cable is normally needed unless a PC is attached; in this case, a null modem cable can be used. Please see Serial Cable Schematic on page 186 for more details.
8 Save these configurations to EEPROM. Enter: save 9 Verify the IP address and netmask. Enter: list stored tcpip These are now stored in EEPROM. 10 After configuration, turn the M208 off, then on. This reboots the M208 and automatically logs you out of the terminal session. 11 Test the equipment and configuration after installation is complete.
Host Configuration When setting up a print destination on a Unix host, you have the option to utilize a computer-aided script such as ezsetup or npconfig or to do all of the appropriate steps manually. If you decide to go with one of the provided installation scripts, select Configure Host Setup from the Main Menu of either program to configure a print setup on your host. It will step you through some questions and then perform all of the necessary setup commands for you.
file is specified, from standard input. The format of the data is not altered by this program so make sure it is in printer-ready format. The syntax for npwrite is: Syntax npwrite ipname portname [filenames] where: Example ipname M208 IP name or IP address. portname I/O port on the M208 (i.e. prn, com1, com2). filenames [optional]. Filename(s) to be printed. If no filename is specified, data is read from standard input. npwrite 192.75.11.32 prn testfile.txt npwrite spike com2 testfile.
• Example on Sun UNIX, either of the following: rsh spike lp -d d1prn < testfile.txt cat testfile.txt | rsh spike lp -d d1prn where spike is the M208’s IP name and d1prn is the destination. Printing Via the Spooler Once you know your communications are correct and you can successfully print directly to the Print Server, you can integrate the spooler. Interface scripts play important roles in BSD spooling environments and especially with System V print spoolers.
ing throughput. Both ezsetup and npconfig utilize the appropriate interface script by renaming it to nprprintername.if, where printername is the name of the printer on the host. To install one of these scripts manually, please refer to the section that applies to your host: the BSD UNIX section starting on page 47 or the System V UNIX section starting on page 51. Custom Interface Scripts If an interface script is to be used for your print setup, you have three choices: 1 Use npr.
translate data to printer format ) | communication program where communication program is the command executing rsh/rcmd/remsh or npwrite so the print job is redirected over the network to the M208. Example ( FILE=$6 #the spool file is found in the sixth parameter on System V cat $FILE | onlcr #filter the job ) | rcmd spike lp -d d3com1 where spike is the name of the M208 and the print jobs are being sent to its destination d3com1 by remotely executing the M208’s lp print command.
BSD UNIX BSD systems allow you to print remotely or to print with an interface file for a locally attached printer. This is configured within the /etc/printcap database. lpd Remote Printing The lpd daemon spools files locally, then sends them to an M208 acting as a remote printer. As interface scripts cannot be used with this spooling method, processing must be done by the Print Server. This method should be used in the following conditions: • your UNIX host supports BSD 4.
To create the necessary entries for this example, these commands are needed: cd /usr/spool/lpd mkdir spike mkdir spike/ps touch spike/ps/log spike/ps/acct chown -R daemon.daemon spike chmod -R g+rwX,o+rX spike Once this is done, you can then start this printer. lpc start ps To send a print job, use this syntax: Syntax lpr -Pprintername filename BSD Interface Script Printing If you decide not to go with a remote printer setup, you can use an interface file instead.
tion of the commands necessary to create these entries: Example hp:\ :sh:pw#80:mx#0\ :lp=/dev/spike.com2:\ :sd=/usr/spool/lpd/spike/com2:\ :lf=/usr/spool/lpd/spike/com2/log:\ :af=/usr/spool/lpd/spike/com2/acct:\ :if=/usr/spool/lpd/spike/com2/npr.if: where hp is the printer name sending jobs to the M208 named spike through the interface file npr.if. To create these entries, please do the following: 1 Create the printer’s spooling directory and associated files.
Host Software on page 31 for more details. COMM_PROG (mandatory) Specify a communication program to transfer data to the M208 (i.e. npwrite, rsh). If the program is npwrite, define the UNIT_PORT variable. Otherwise, define the LP_DEST variable. PRINTER_TYPE (mandatory) Specify printer type (i.e. raw, ascii, ps, hp, pclps, gen7170). UNIT_NAME (mandatory) Define the M208 IP name. UNIT_PORT (conditional) Specify the M208 port name (i.e. prn, com1, com2). Use only when COMM_PROG is defined as npwrite.
6 Syntax Try printing with the following syntax: lpr -Pprintername filename System V UNIX Printing in a System V environment requires the use of an interface file. It also consists of: • the lp printer interface program, • the lpsched printing scheduler, • a set of programs that act as interfaces between scheduler and printing device. The scheduler copies the file into a spooling directory and calls the interface program when the job is ready to go to the M208.
Setting up an Interface Script The following steps are the manual instructions for setting up your host with npr.if: Note The example commands provided represent a print setup involving a printer named hp, an M208 named spike, and a printer attached to the M208’s com2 port. 1 Copy the nprsysv.if file from the host software medium to the model directory. Copy the file as npr.if or name it something more meaningful. cp nprsysv.if /usr/spool/lp/model/npr.if 2 Note Edit the npr.
Example #END_MARK_1 NPDIR_PATH=/usr/local/bin COMM_PROG=rcmd UNIT_NAME=spike LP_DEST=d4com2 PRINTER_TYPE=hp BANNERPAGE=1 #START_MARK_1 Note Additional variables can also be defined within this variable section as indicated by BANNERPAGE=1. Some other options are ASCII to PostScript conversion, carriage return insertion, and scrambling. By setting a particular variable to a 1, this option is then turned on and a 0 turns it off. These too are described further in the beginning of npr.if.
npd Pseudo-device Interface The npd pseudo-tty daemon is used when bi-directional communications is required between the printer and printing application, and when changes to the printer’s interface script are undesirable. Some applications like Sun NeWSprint and Adobe TranScript work best with a bidirectional communications channel to the printer because they can provide more details on the printer status. For example, PostScript printers can send error messages back to the application as they occur.
Starting npd Starting the npd daemon is all that is needed to utilize npd. Integrating any special applications can then be done anytime thereafter. Use the following syntax to start npd: Syntax npd devicefile ipname portname where: devicefile Name for a pseudo-tty pair’s slave device acquired by npd. ipname M208 IP name or IP address. portname M208 I/O port name (i.e. prn, com1, com2). Note The devicefile cannot exist prior to starting npd and this particular npd daemon cannot be running already.
default). You can modify this value with the -t option. Example npd -t 60 /dev/spike.com2 spike com2 for the timeout to occur in 60 seconds. Testing npd Once npd has been started, it’s a good idea to test and see if npd is working before trying to print through the spooler. This is one test method. Example cat test.txt > /dev/spike.com2 redirects the cat output of test.txt to the npd device /dev/spike.com2 which is then sent to the M208 named spike.
devicefile Example Name linked to the slavefile by npd. 153 spike com2 /dev/ptyq1 /dev/ttyq1 /dev/spike.com2 is the log entry for the npd daemon using process ID 153. You can acquire the process ID of the npd daemon that needs to be stopped and then execute the following kill command for that process: Syntax kill -TERM pid Applications Using npd Sun NeWSprint Sun NeWSprint page accounting works with PostScript printers.

use /dev/ttypa as the device interface for any port on the M208. When the program creates the spooling directory and entry in /etc/printcap file, set the lp= field to the devicefile argument from npd. Example For a PostScript printer named ps attached to com1 on the M208 named spike: ps|PostScript|PostScript on spike’s com1 port:\ :lp=/dev/spike.
Select p as the port number. Select ppa0 as the adapter. Select a printer type that best matches what you are using. Select a device lp0. If this device is not available, go back and select “Remove a Printer/Plotter” and remove lp0 making it available for your next run through. AIX has a limit of four physical devices. If you run out, IBM suggests deleting the device after completing a print setup thus making it available for future setups. 3 Create a new queue.
This is the /etc/qconfig entry created for this particular setup: Example queue2: device = lp0 up = TRUE lp0: backend = /usr/lib/lpd/piobe queue stanza by mkquedev (queue device) printer’s ready to go queue device stanza for local printing For further information on these commands, please see your AIX system documentation. Other TCP/IP Print Methods NCSA NCSA is a freeware package available on the Internet at zaphod.ncsa.uiuc.edu in the directory /PC/Telnet/msdos/contributions. The file is tel23bin.zip.
Note FTP’s package also provides Windows printing along with several other software packages on the market. These are just two possible applications that will work with the M208. Please see the user manuals of the appropriate applications for more information. Direct Socket Printing The M208 provides a socket interface for custom printing applications. Programs can open a TCP connection to a TCP port on the Print Server.
CONFIGURING THE M208 FOR NOVELL Overview This chapter introduces the M208’s configuration possibilities along with the various methods of printing available within a Novell environment. The M208 works with different NetWare versions, including version 4, and we provide setup steps for each. Host Software NetWare’s PCONSOLE is generally used to change passwords, add print servers, add remote printers, and add queues to be serviced. It can be used for both a PSERVER or RPRINTER setup.
To communicate with the unit using npsh.exe, you need to: 1 From a DOS prompt on a Novell workstation, begin an npsh session with the unit. npsh unitname Starts a Telnet-like session with the named M208 with guest access only. 2 To obtain root access to the unit, type: supervisor A standard login screen is displayed prompting you for the login name and password. 3 Login to the unit as a root user. root Root users require the use of a password as configured in the unit’s user list.
Host Configuration The M208 can act as either a PSERVER or as a RPRINTER in a Novell environment. It supports encrypted passwords and it is capable of servicing up to 16 file servers and 32 queues as a PSERVER. One M208 can handle eight RPRINTER setups. PSERVER Bootup When booting as a PSERVER, the M208 gets a server list from the first file server it contacts. The unit then contacts those servers on that list to see if there is a queue that needs servicing.
66 Step Action Result of Action 1 Log in to Novell as supervisor. Gives you supervisor rights. 2 Enter PCONSOLE. PCONSOLE’s Main Menu displays. 3 Select PRINT QUEUE INFORMATION. List of currently-defined queues comes up. 4 Press to add a queue. Asks for new queue’s name. 5 Type in this new name in any format you like and press . New queue is added to list. 6 Press . Returns to PCONSOLE’s Main Menu. 7 Select PRINT SERVER INFORMATION.
Step Action Result of Action 14 Type in the name of one of the eight default destinations on the unit for the Name field (e.g. d1prn, d3com2, etc.) and go to the Type field. Cursor sits at the Type field with a printer name now assigned. 15 Press at this field and then select DEFINED ELSEWHERE. Comes back to the PRINTER N CONFIGURATION window. 16 Press and select Yes to save changes. Gives you the option to define more printers. 17 Press again.
This procedure associates an existing PSERVER with a remote M208 acting as a RPRINTER in a pre-NetWare 4 environment. It is the PSERVER’s responsibility to get jobs from the queue and to pass them off to the M208 acting as the remote printer. Unlike a PSERVER set-up, the M208 does not deal directly with the queues. Note As a RPRINTER, the M208 does not use a login ID. In addition, a non-M208 PSERVER (e.g. PSERVER.NLM) must be running for RPRINTER to operate.
Step Action Result of Action 6 Press . Returns to PCONSOLE’s Main Menu. 7 Select PRINT SERVER INFORMATION. A list of existing print servers displays. 8 Select one of the print servers and press . Display’s PRINT SERVER INFORMATION menu. 9 Select PRINT SERVER CONFIGURATION. Brings up this menu. 10 Select PRINTER CONFIGURATION. Displays a list of printers associated with the print server.
Step Action Result of Action 20 Press to use the default. Usually this is fine. Returns you to the queue list. 21 Press until you have exited PCONSOLE. You’re now at the command prompt. 22 Start PSERVER. Starts the PSERVER so the M208 can service it as an RPRINTER. 23 In SYS VOLUME on the file server, change to the \LOGIN directory. You will be at this prompt. 24 Create a directory named after the M208.
NetWare 4 Options NetWare 4 introduces NDS and some new frame types. The M208 can be used in a NetWare 4 environment with either of these options: Note • Set the M208 up as a PSERVER replacing a dedicated workstation running PSERVER.EXE or PSERVER.NLM on the file server. The M208 replaces these loadable PSERVER’s so they are no longer needed. • Set the M208 up as a RPRINTER interacting with an existing PSERVER. If following a PSERVER setup, bindery emulation is required.

CONFIGURING THE M208 FOR APPLETALK Overview This chapter will cover the few steps required to get your print jobs printing to an M208 in an AppleTalk over EtherTalk environment. Note The M208 does not support LocalTalk. M208 Configuration An AppleTalk setup does not require any Print Server configuration; the network parameters are automatically configured for you once the M208 is booted on the network. If you wish to modify some of the M208’s default settings, you can use the built-in npsh command set.
M208name_papname where M208name is the name of the M208 and papname is an M208 I/O port. Both names are configurable. M_000BF5_prn Example is the printer associated with the M208 named M_000BF5 using the parallel port. The Print Server’s default name is M_xxxxxx where xxxxxx equals the last six digits of the unit’s Ethernet address found on the bottom of the unit. Note 3 From the list of printers, select one to print to. You have now configured your AppleTalk system to print to the M208.
store pserver name Sales This new name will also affect Unix, Novell and NetBIOS setups. Note 3 Enter the name that you would like to appear for the papname (e.g. laser). This will make up the second part of the name in the Chooser. store pserver applepap prn name laser 4 Reset the unit so the changes take effect.
Disabling the AppleTalk Module If you have several Microplex M208s in your network and only some of them are servicing AppleTalk networks, it is a good idea to turn off the entire AppleTalk module from the particular M208. This will not only save on M208 resources but will ensure that only appropriate M208s show up in the Chooser. To disable the AppleTalk module, start an npsh session with the unit and follow the steps below: 1 Remove AppleTalk from the available protocols.
CONFIGURING THE M208 FOR WINDOWS Overview This chapter discusses the M208’s support for Windows. The M208 provides support for Windows NT, Windows for Workgroups (WfW), and Windows 95. Examples are provided for each of these environments. In a Windows environment, TCP/IP is the data transfer protocol used for printing. This means that IP addresses and netmasks are required in your Windows stations along with the appropriate TCP/IP software.
NetBIOS is further broken down into these two setup procedures: “net use” - Microsoft’s shared resource feature. Print Manager - Microsoft’s management tool for printing. Choosing one of these methods depends entirely on what’s available with your particular Windows software.

Fill in the IP address and netmask for this workstation and then click OK.
Through the COM Port on page 40 for detailed instructions. Once you have configured the unit, you will notice the STAT LED flashing on once per second. This means the M208 is configured and recognizable on the network. At this point, you can now configure your host. Host Configuration Now that your workstation(s) and the M208 have IP addresses and netmasks, you can now configure a print setup. There are several methods available depending on what Windows package you are using.
Line Printer Daemon using TCP/IP. NetBIOS Using Print Manager Method Note In order to use this method, you must first configure the M208 with a Microsoft Networks Workgroup name. This can be done by telneting to the M208, starting an npsh session with the unit, and issuing the following command: store pserver smb workgrp workgroupname where workgroupname is the name of the Microsoft Networks Workgroup that you want the M208 to be included in (e.g. Engineering).
Windows for Workgroups (WfW) NetBIOS Using Print Manager Method Note In order to use this method, you must first configure the M208 with a Microsoft Networks Workgroup name. This can be done by telneting to the M208, starting an npsh session with the unit, and issuing the following command: store pserver smb workgrp workgroupname where workgroupname is the name of the Microsoft Networks Workgroup that you want the M208 to be included in (e.g. Engineering).
works Workgroup name. This can be done by telneting to the M208, starting an npsh session with the unit, and issuing the following command: store pserver smb workgrp workgroupname where workgroupname is the name of the Microsoft Networks Workgroup that you want the M208 to be included in (e.g. Engineering). Note You must reset the M208 for this command to take affect. 1 Ensure that the network connection is functioning properly between the Windows workstation and the M208.

unit host unit host M208 INTERNAL ARCHITECTURE Overview This chapter will provide a more detailed description of the internal operating architecture of the M208 including: destinations, models, variables, logpaths, and I/O ports. Destinations The M208 provides six printer destinations that are used by all hosts. A destination can be thought of as logical place on the M208 to which hosts send their print jobs. Destinations allow you the ability to configure a number of different print setups on the M208.
unit host Models Each destination on the M208 also has a model associated with it. The six models (one per destination) can be thought of as a series of mini-filter that can do special processing to the print job data. These processing options include: • banner page generation, • header string insertion, • trailer string insertion, • tab expansion (xtab), • carriage return insertion (onlcr), • ASCII to PostScript conversion (a2ps), • print job descrambling.
unit host Table 3: Model Types Setting Inclusions pcl-ps For printers that cannot autosense the print job format and switch modes by themselves. Precedes each job with a string to switch from PostScript to PCL, or vice versa, depending on job content. These strings must be specified in the setup command. a2ps Convert ASCII jobs to PostScript or pass PostScript jobs directly to PostScript printers.
unit host Logpaths The term logpath comes from the UNIX syslog logging system. With the M208, each destination can report statistics on: user, page count, job name, and printer errors. In addition, a checksum calculation can be obtained to confirm data integrity when a job is sent to the printer. Logging occurs either through a printer or terminal connected to an I/O port, or through a Telnet session to a particular TCP port.
USING THE M208’S COMMAND SET Overview At this point in the manual, you should have your M208 installed and configured on the network and at least one host configured to print to it. This section’s purpose is to give you the basic tools to add to your print setup by introducing the Print Server’s command set. npsh Overview On the Print Server itself, is an entire command set, npsh, allowing for M208 parameter configuration, display, and execution.
npsh Prompt When npsh is accessed through a Telnet or COM1 terminal session, a prompt is displayed after login to indicate that it is ready to accept a command from the user. The Telnet prompt is formatted ipaddress:userid> where ipaddress is the IP address of the M208, and userid is the user ID of the currently logged-in user. Example 192.75.11.32:root> where 192.75.11.32 is the M208’s IP address and the user is root. The COM1 I/O port’s login prompt is formatted userid>.
Examples list tcpip > prn sends current network settings to the first parallel port. chr $FF > prn sends a formfeed to PRN. npsh Basic Commands Before reading on about the M208’s command set, it is important to understand some of the basic commands involved. Set commands affect only current settings, not stored settings in EEPROM. The save command is used after set to save the new settings to EEPROM. Store commands only affect stored settings in EEPROM but not the current settings.
examples for a particular command are provided at the end of that command’s main section and when another command or other information may be useful, a reference is given. cancel cancel jobid Delete a job from the M208’s internal queue.

126 USING THE M208’S COMMAND SET: npsh Command Set
USING NPWIN Overview NPWin is an SNMP-based software utility that allows you to perform all unit configuration and management in a point-and-click, Windows environment. NPWin provides all the same configuration and management functionality available with the built-in npsh command set. NPWin also includes an extensive, context-sensitive, on-line help system to explain the features and how they work. System Requirements NPWin requires a workstation capable of running Windows 3.11, Windows NT, or Windows 95.
4 Change to the specified directory, and double click on the NPWIN.EXE icon to launch the software. Print Server/Hub Configuration NPWin allows you to configure the M208 in a point-and-click, graphical environment.

USING THE M208’S ADDITIONAL OPTIONS Overview As of now, you will have configured your M208 and you’re probably printing to it successfully. The purpose of this chapter is to enhance your print setup by describing some of the additional features that the M208 provides.
on page 140 for more information. Setting passwords and assigning a permission level to users eliminates the possibility of any unwanted users from getting into the M208’s command set and manipulating the current settings. To configure passwords and to learn more about the two different permission levels provided for users, please see set user on page 117 and User Accounts and Permissions on page 94. To view the current user settings, see list user on page 102.
them on the host within an interface file, nprbsd.if or nprsysv.if, or on the Print Server itself. The choice is completely up to you. Automatically you are given the choice between six different destinations on the M208 allowing for six different possible print setups; each of these print setups is defined by the extra processing specified by it’s associated model. It is the model that defines most of these extra processing options.
Capturing Printer Feedback One of the key aspects of maintaining a computing environment is monitoring printer status and logging this information to useful places. The M208 allows just that through logpaths or through a backchannel method. In addition, the Print Server’s lp command provides parallel port printer status and job information as a user sends a job. Logpath Method The easiest and most reliable method is to utilize the many logpath options available on the Print Server.
Lp Method The M208 provides its own version of the lp print command. This is used in conjunction with rsh/rcmd/remsh within an interface script or directly from the command line on the host. By default, it provides parallel port printer status and can also be configured to report incremental byte counts as the job prints. It can also show the job position in the M208’s queue as it moves to the top. Note Using lp will provide printer error messages as well as job status.
Two methods are available for doing this: 1 physically moving jumpers inside the Print Server, 2 issuing a command on the M208 and rebooting. Either way will produce an M208 that has all of the network settings it came with originally. Each method is described next. Through Jumpers For normal operation, the unit has its S3 strap on pins 1 and 2 for EEPROM Enable. Moving the strap from this position to pins 3 and 4, or DEFAULT IP, will override your network settings and put the unit to factory defaults.
Figure 5: M208 Jumper Settings P2 P1 S3 EEPROM ENABLE DEFAULT IP Getting Ready for Complex Networks The default settings on the M208 allow printing in a simple network without routers. You need to add routing information to communicate or print from hosts on other networks. To do this, you can establish either of the following: • default routes for generic or unknown network addresses to use, • static routes to known network addresses such as a particular host or network.
• using npconfig’s Detailed Configuration Options Sub-Menu, • using the FTP Daemon, • through an SNMP manager. Maintaining Network Security Besides the general security measures mentioned in Network Security on page 131, the M208 provides two more for TCP/IP environments. These include: • a TCP access list, • scrambling/descrambling of print jobs.
To utilize this feature, you need to: 1 Look into the npscramble.c source code for a variable called SR_KEY. This contains a four digit hexadecimal value to be used as the descrambling key on the M208. 2 Log into the M208 as root user and set this value as the key. Enter: set sysinfo descramblekey key 3 Set descrambling on in the model you are utilizing. Enter: set model modelname stty descramble 4 Save these new settings.
In addition, ping is provided for testing TCP/IP configuration parameters and network connections with target hosts. Please see ping on page 103 and telnet on page 124 for command details. Novell Options Setting Password Security Besides the general security measures mentioned in Network Security on page 131, a Novell setup provides further password security. A password can be set on the M208 and within your PCONSOLE setup so that when the M208 tries to login to the file server, the passwords are compared.
1 Login to the M208 through an npsh session as a root user. 2 At the npsh prompt, enter: store pserver novell fserver add fservername where fservername is the name of the Novell file server you want to add as a preferred file server. This adds the specified file server as a preferred file server on the M208. 3 Repeat steps 1 and 2 to add additional preferred file servers. For more information, please see store pserver novell fserver add fservername on page 121.
The M208’s custom MIB definition file is included on the host software disk in a file called mplxmib.txt. This file can also be downloaded from the Microplex FTP site (ftp.microplex.com: support/m208/misc/mplxmib.txt) or can be accessed via the Microplex Web site (http://www.microplex.com/). Custom MIB Variables The variables found within the custom MIB definition file describe every type of internal information that can be accessed on the M208 by an SNMP manager.
coldstart A generic trap generated every time the M208 is powered on or reset. authenticationFailure A generic trap generated whenever a disallowed access is attempted. lpqIOStatusChanged The only custom trap. This trap is generated whenever an I/O port’s status changes. Note No trap is generated on a CTS change on the serial ports, only on a DCD change.
SNMP Security SNMP does not include any formal type of security definition. However, security can be accomplished using communities. A community is a string that is sent with every SNMP request and is used to define a certain view of the MIB. By doing this, you can control what parts of the MIB are accessed by SNMP managers. To access the M208’s custom MIB, the public community string can be used to read any variable that have read access.
the Microplex Web site (http://www.microplex.com/). 2 Compile this MIB description file to work with your SNMP manager. 3 Using your SNMP manager, view the particular MIB variables that you wish to monitor. Note If you are using Sun’s SunNet Manager, you will need to download a special MIB file (ftp.microplex.com: support/m208/misc/mplxmib.txt.SNM) from the Microplex FTP site.

The actual syntax of the commands will depend on the particular SNMP manager you are using. echo “trapCommunity[1]=\”building-A\”” | snmp-set spike custmmib where building-A is the string that you want the M208 to send with the trap information. This community string has a 14 character maximum. echo “trapDest[1]=192.75.11.11” | snmp-set spike custommib where 192.75.11.
The following is the structure of the file system you will see when you ftp to the unit: /queue Contains three files with information pertaining to the print queue associated with each of the M208’s ports (i.e. prn, com1, com2). These files allow you to view the current status of each queue. /dest Contains six subdirectories, one for each of the six print destination on the M208. Please see Destinations on page 89 to better understand destinations and printing.
4 Change to the /dest directory that you want to print to. cd dest/destinationname 5 Change the mode to correspond to the type of file to be printed. Choose binary mode if the file to be printed contains both text and graphics and ASCII mode if the file is text only. The default mode is always ASCII. bin 6 Copy the file you want to print to this directory. put filename The file is spooled and printed. 7 Logout of the FTP session.

their syntax. The configuration file can be seen as simply a user-defined script that includes a number of configuration commands to be executed. Comments describing the configuration can also be included in this file provided they follow the correct syntax. The following is an example of a simple configuration file: Example ; These are comments for the example config file. ; Note that comments have to start at the beginning of a ; line and be preceded by an ‘;’ ; version 5.
It is important to ensure that the redirect port's parameters are not altered in commands that follow or else the output may be affected. Note It is not possible to generate a text configuration file from an existing binary configuration file in the /config directory. Executing a Configuration File Using FTP The following example shows how to execute a configuration file using FTP: 1 Change to the local directory where the text configuration file resides. 2 Login to the M208 using ftp.
Serial Line IP Serial Line IP (SLIP) is a protocol used to connect two networks using a serial line. The M208’s serial ports support SLIP allowing the M208 to be used to provide remote hosts with dial-up access to the local network via a modem. SLIP is a very simple protocol and does not have any type of packet identification, error detection/correction, or address configuration. It relies on upper level protocols (IP, TCP and UDP) for such tasks.

The baud rate must correspond to the baud rate of the attached modem. Note 2 Add a route to the M208’s routing table for the remote host. store tcpip route add host [remotehost ipaddress] [remotehost ipaddress] [ioportname] Example store net route add host 192.147.242.3 192.147.242.3 com1 3 Configure the M208 to answer ARP requests for this remote host so that anything destined for this remote host will go to the M208.
npsh mode when the remote computer is turned off. Note A serial port cannot be configured as both a SLIP connection and a print server destination. Any destinations that are configured to the serial port must be reconfigured to another I/O port. For more information on SLIP, please see set com1|com2 on page 105. IP Routing IP routers allow computers connected to two (or more) separate networks to communicate with each other.

? ? TROUBLESHOOTING THE M208 Overview This chapter will help you with various problems you may encounter throughout your print setup or when printing. There are five main sections in this chapter: 1 Common Problems 2 TCP/IP Problems 3 Novell Problems 4 AppleTalk Problems 5 Windows Problems. Common Problems ? The M208 doesn’t power up with the correct LED sequence Please refer to LED Patterns on page 188. This table describes different LED startup patterns that are possible on the M208.
? • Have you checked your network connection to the M208? Try it at a new location on your network if possible or swap in another device. • Have you made an entry in your host table (/etc/hosts, host nis map, or DNS name table) for the M208? • Have you tried to ping with the IP address instead of the IP name? This will eliminate any name-lookup issues and focus more on the communications between the M208 and your host.
? ? You cannot Telnet to the M208 If you are unable to ping the Print Server as well, please see Communication Related on page 159. If it is telnet only that you are having problems with, these points should be considered: • Are you able to telnet to another host on your network or telnet from another host? If not, look into your host’s TELNET configuration.
? • If you’re using npr.if to print, are the host binaries installed on your system in a general directory such as /usr/local/bin? Please see Printing Via the Spooler on page 44 for more on interface file printing. • Are there any error messages in your email, a log file, or other standard error files on your particular host? These messages can be very helpful in narrowing down the problem.
? somewhere in the print path. Any printing from PCs should have a “raw” setup. Note Some other things to consider when garbled data persists are: • tab expansion (xtab) set on with graphic jobs, • cable used between the M208 and the printer, • type of flow control being used on the M208 and a serial printer. If you cannot eliminate the garbling, you may want to try printing without the Print Server to see if the problem persists.
? Note M208 destinations are case sensitive so they will not be recognized if they are typed incorrectly. By default, they are all in lowercase. If you are setting up in a NetWare 4 environment, the destination must be renamed to uppercase to match PCONSOLE’s entry. Please see set dest on page 107 for information on changing names. • In a PSERVER setup, did you ensure that you were in bindery emulation mode? If you were, then did you do your entire print setup (i.e.
? Printing Related ? The job goes to the queue but nothing prints If nothing is printing, make sure you have a connection to the M208 first. Please see Communication Related on page 163 if you are having connection-related problems. Otherwise, consider these points to solve any printing problems you may be having in your Novell environment: • Does the job leave the queue or is it stuck there indefinitely? If it leaves properly, the problem points to the actual printing mechanism on your Novell system (i.
? ? The job prints but it comes out incorrectly This category really can be broken down into several sub-categories such as lost characters, garbled data, extra banner pages, or blank pages at the end of the job. However, the reason for these mishaps can generally be traced to the printing mechanism used on your Novell system. These points should be considered when configuring your print method (i.e. CAPTURE, NPRINT, etc.
? AppleTalk Problems ? The Laserwriter icon in the Chooser Menu doesn’t display any printer destinations In this situation, these things should be considered: • Are you using EtherTalk rather than LocalTalk or TokenTalk? • Is “EtherTalk” chosen in the Control Panel’s Network icon? • Have you checked the M208 and the Apple system’s Ethernet connections? • Have you configured the M208 to show up in the correct AppleTalk Zone. Please see AppleTalk Zones on page 76 for information on doing this.
? printer is cleared of any error situation and the “blocked” message goes away, the print job should then go through and the queue should move along properly. However, if the printer is in fact online and ready to print but you’re still seeing “blocked” messages, there may be a problem with the communications between the M208’s I/O port and the printer. Possibly the cable is faulty and the send signal isn’t getting through to the M208 or maybe the printer and M208 aren’t communicating properly.
? ? Printer and Network Errors Anytime you have several Windows for Workgroups (WfW) stations printing directly to a M208, you may run into various printer and network errors. The problem occurs when one station is sending a print job to the printer and another station tries to send a print job to the same printer at the same time. The M208 tells the second station to hold on to its data until it has finished with the first job.
