8 ETHERNET PRINT SER VER 2. Introduction 2.1 Description The Ethernet Print Server (EPS) is a multiprotocol print server. It provides network access to printers for a variety of network protocols and operating systems. It has an AUI port for connection to an external Ethernet transceiver, and an RJ-45 connector for use with 10BASE-T.
9 CHAPTER 2: Introduction If you cannot move a switch by hand, use a small screwdriver or pen to gently flip the switch. Make sure each switch is fully in the On or Off position; inconsistent operation may result if the switch is between settings.
10 ETHERNET PRINT SER VER 2.4 EPS Configuration Depending on your network, the EPS might work properly right out of the box with no additional configuration. If your network installation will use the AUI port instead of 10BASE-T, you will need to change one of the DIP switches before you install the unit.
11 CHAPTER 2: Introduction In all three cases, the EPS is transparent to the user and uses normal print syntax from the host—simply specify the file and queue name in the print command.
12 ETHERNET PRINT SER VER 3. Installation This chapter covers only the installation of the EPS in the network and attaching the print devices. For details on installing the optional RTEL software or installing a new download image (to re-load the EPS’s code in the Flash-ROMs) see Appendix E.
13 CHAPTER 3: Installation 4. If Sw2 is off, the EPS will print status information to the serial port as it boots. Attach a console device (we recommend using a terminal) to the serial port of the server. The default serial port settings are 9600 baud, 8 bit characters, and no parity.
14 ETHERNET PRINT SER VER After the EPS loads the Flash code and the unit is running normally, the OK LED will blink once each 2 seconds. Depending on SW2’s position, the EPS will print a greeting to the serial port when the unit is operational: Ethernet Address: xx-xx-xx-xx-xx-xx IP Address: undefined Lantronix EPS1 Print Server Diagnostics Report: Interface: 10BASE-T Memory: 256KB Gate Array: Vers 3 Errors Reported: None Attempting BOOTP: no reply received.
15 CHAPTER 3: Installation 3.1 How Do I Know It’ s W orking? If the EPS appears to be working (OK LED is blinking slowly) and the unit is connected to the network, there are various ways to confirm that the unit is visible to network hosts: • If the EPS has an IP address, you can PING it from a TCP/IP host — the EPS should respond correctly.
16 ETHERNET PRINT SER VER If a terminal is not attached to the serial port, you can still detect a boot error (typically network-related) via the LEDs. If the OK and network LEDs are blinking rapidly (2-3 times per second) in unison, a boot failure occurred.
17 CHAPTER 4: Host Configuration 4. Host Configuration Host configuration is broken down by protocol, since none of the procedures are common to any of the protocols. You must enable the protocol on the EPS service before clients will be able to see and use that service.
18 ETHERNET PRINT SER VER You must perform these steps on each file sever that will need access to the EPS queues. Users on each file server wishing to print will specify the file server’s queue name; the file server and EPS will decide which, if any, of the EPS’s queues can service the requests.
19 CHAPTER 4: Host Configuration Use the arrow keys to select “Supervisor Options,” and press <Enter>: Supervisor Options Default Account Balance/Restrictions Default Fine Restrictions -> Edit System Autoexec file File Server Console Operators Intruder Detection/Lockout System Login Script View File Server Error Log Workgroup Managers Fig.
20 ETHERNET PRINT SER VER Press <Insert> to create a new entry and add the EPS1 name (EPS_xxxxxx by default) and hit <Enter>. Enter Print Server Name:EPS_xxxxxx This is the name that the EPS will log in as when querying the file server’s print queues.
21 CHAPTER 4: Host Configuration 3a. Highlight the queue you just entered and press <Enter> to configure the queue itself. The menu shown in Fig. 3-5 will appear. Print Queue Information Current Print job entries Current Queue Status Currently Attached Servers Print Queue ID Queue Operators -> Queue Servers Queue Users Fig.
22 ETHERNET PRINT SER VER 4. When you desire no other configuration, you need to tell the EPS to re-scan the file server queues since you modified them. Return to the main “Available Options” menu, highlight “Print Server Information,” and press <Enter>.
23 CHAPTER 4: Host Configuration Highlight “Server Info” and press <Enter>. The menu shown in Fig. 4-10 appears. Print Server Info/Status Print Server Version: 3.0.xx Print Server Type:Dedicated DOS # of Printers n Queue service modes 0 -> Current Server Status Running Serial Number 066497 Fig.
24 ETHERNET PRINT SER VER The Berkeley remote printing system is supported on many machines, and is simple to configure for the EPS. You need to add the host queue name into /etc/printcap, and then specify the remote nodename (EPS) and the service name on the EPS.
25 CHAPTER 4: Host Configuration 4.3 Optional R TEL Functionality Using the native lp or lpr print utilities requires installing and configuring the RTEL software on the host—see Chapter 7 for details. After installing the software and configuring connections to the EPS1, print commands will look like normal printing commands.
26 ETHERNET PRINT SER VER Macintosh computers that do not support EtherTalk will need either an Ethernet card or an EtherTalk-to-LocalTalk™ router to use the EPS. If you use a router, it will provide an EtherTalk zone on the LocalTalk network, and the EPS devices will appear under that zone.
27 CHAPTER 4: Host Configuration $ RUN SYS$SYSTEM:LATCP LCP> CREATE PORT LTAnnnn/APPLICATION LCP> SET PORT LTAnnnn/node=nodename/port =portname LCP> SHOW PORT LTAnnnn LCP> EXIT Above, nodename is the name of the EPS (EPS_xxxxxx) and portname is the name of the EPS print port to use (Port_1 is the serial port, Port_2 is the parallel port).
28 ETHERNET PRINT SER VER A print request might then look like $ PRINT/QUEUE=EPS_PARALLEL filename.txt Using the SHOW QUEUE/FULL command under VMS will show the setup characteristics of the VMS queue and what jobs are pending in the queue. 4.6 T roubleshooting the Printing Process You can troubleshoot print queues in a number of steps.
29 CHAPTER 4: Host Configuration If printing from NetWare, make sure you entered the server’s name and login password correctly under the PCONSOLE setup. If the EPS cannot log into the file server correctly, your job will not print. Also, make sure the EPS server name is one of the Queue Servers for each queue — if it is not, you will be able to log in, but the EPS will not be able to obtain information about queued jobs, so it will never print the jobs.
30 ETHERNET PRINT SER VER • Check that flow control of some sort is enabled. Characters dropped during a PostScript job will generally cause the job to fail. You might also try attaching a terminal to the EPS print port and sending a small print job, and observe any obviously missing or corrupt data.
31 CHAPTER 5: Protocol Overview 5. Protocol Over view The EPS supports 4 major protocols: NetWare, TCP/IP, AppleTalk (EtherTalk), and LAT. The 4 protocols provide varying support for printing, and each is discussed below. For all 4 protocols: On the EPS, the term “service” denotes a printing resource that another node can access.
32 ETHERNET PRINT SER VER 5.1 NetW are NetWare allows any networked node (a “client,” usually a PC) to access another node (a fileserver) as if it were locally attached. You can use hard disks, printers, and other devices as if they were directly attached to the client station.
33 CHAPTER 5: Protocol Overview The EPS provides two major methods of printing via TCP/IP. Berkeley Remote LPR is supported, as is the RTEL software. Both methods provide queueing of jobs on the host if the host is busy with another job. The remote LPR software allows the EPS to look like another host that can spool and print files, and hosts wishing to print to the EPS simply send the print data and assume the EPS will handle it properly.
34 ETHERNET PRINT SER VER An AppleTalk zone name is configurable, in case there are multiple zones on the LAN to which the EPS is connected. If you are using the default zone or only one zone, you do not need to configure any information on the EPS.
35 CHAPTER 5: Protocol Overview LAT is disabled by default on services provided by the EPS. This is because many network managers object to the frequent LAT service announcements. If you desire LAT on these services, you can easily turn it on. You can also configure LAT hosts to connect directly to a physical port on the EPS, eliminating the need for service announcements, but still providing LAT printing.
36 ETHERNET PRINT SER VER 6. EPS Configuration In many cases, you may not need to configure the EPS to use it as a print server. Using NetWare and AppleTalk is especially simple. To print using LAT and TCP/IP, you may need to follow some of the setup instructions listed below.
37 CHAPTER 6: EPS Configuration TCP/IP users may want to set a TCP/IP address or gateway host (SET SERVER IPADDRESS or GATEWAY commands). You might need a gateway host if you have routers on your network and wish to print from non-local networks. The EPS will listen for routing packets (RIP, OSPF, etc.
38 ETHERNET PRINT SER VER 6.3 Port Characteristics You can change all port settings via the SET (or DEFINE) PORT commands. Since the ports logout after each print job, you will generally want to use only DEFINE to configure them. You can LOGOUT the port to force the new settings to take effect.
39 CHAPTER 6: EPS Configuration refer to both physical ports. For example, you might want an AppleTalk service named “LAB_APPLE” and a NetWare service named “NETW_LASER,” both pointing to the serial port on the EPS. Both queues will accept jobs simultaneously, and jobs from both queues will print on the serial port in the order in which they were queued.
40 ETHERNET PRINT SER VER 6.5 NetW are Configuration You do not need to configure the EPS for use with NetWare. The NetWare address is the EPS’s hardware address, and the EPS discovers the network by listening to network traffic. The EPS contacts file servers in the same way.
41 CHAPTER 6: EPS Configuration 1. Flow control must be enabled; if any characters are lost in transmission, the entire job will likely fail and the printer may hang. X-ON/X-OFF (the default on the EPS) is acceptable. 2. 8-bit characters (also the default) must be enabled for PostScript jobs to be sent to the printer correctly.
42 ETHERNET PRINT SER VER The SHOW PROTOCOLS LAT command shows all current configuration and counters for the LAT protocol handler on the EPS. SHOW QUEUE will show any currently queued or active LAT print jobs. SHOW NODES and SHOW SERVICES will show other available LAT resources, and is an easy check of your LAT network.
43 CHAPTER 7: UNIX/RTEL Host Setup 7. UNIX/R TEL Host Setup This chapter explains how to set up your UNIX host to take advantage of the Reverse Telnet software. Reverse Telnet allows your UNIX host to form connections to the EPS, through the host’s print queueing system, a device interface, or with applications such as Telnet and Rlogin.
44 ETHERNET PRINT SER VER not support all the data-processing options that the printer interface does. It cannot be configured to generate a banner page, for example, or perform tab expansion. The options for the printer-interface method are not valid with the device interface method.
45 CHAPTER 7: UNIX/RTEL Host Setup In general, rteld is the only application that users might have to run interactively. The lp and lpr filters are called by the host’s printing subsystem. 7.2 Installing the Reverse T elnet Software This section describes the procedure used to install the Reverse Telnet software (RTEL) on a UNIX host machine.
46 ETHERNET PRINT SER VER To install and configure the RTEL software: 1. Log into the host machine as the super-user. Set your current directory to /tmp/rtel (or whichever directory the ETS software was initially loaded into). 2. Execute the RTEL install script by typing “.
47 CHAPTER 7: UNIX/RTEL Host Setup NOTE: The target print service does NOT have to be local to the EPS. The EPS will search remote services if the service specified is not local. You can access any available LAT service through the EPS in this manner.
48 ETHERNET PRINT SER VER 5. The mkprt script will add the following information to the /usr/spool/rtel/server_hosts file: queue_name server service passwd options Queue_name is the name of the UNIX print queue; passwd and options are configurable parameters for the print queue.
49 CHAPTER 7: UNIX/RTEL Host Setup There must be an entry in the options field (use “none” if no options are desired). Multiple options can be specified, separated by commas. Options must be specified in lower case characters. There must be an entry in the server_hosts file for each EPS print queue you wish to use.
50 ETHERNET PRINT SER VER For UNIX systems that use the lpr spooling system, delete the entry for the printer in the “/etc/printcap” file. You also may want to delete the entry for the printer in the RTEL directory. 7.8 Creating R TEL Pseudo-Devices For each RTEL pseudo-device you wish to create, the EPS must execute the rteld command.
51 CHAPTER 7: UNIX/RTEL Host Setup queue_name server service passwdoptions rprint1 eps1 prt_srvc null banner /dev/ttyq1 eps2 mod_srvc null -q /dev/ttyq6 eps2 :4 null -q The second line will request a connection to EPS “eps2” and service “mod_srvc”, using pseudo-device ttyq1.
52 ETHERNET PRINT SER VER 7.10 R TEL T roubleshooting There is a diagnostic file in the /usr/spool/rtel directory that may be helpful in finding problems. The job_status file contains any errors that occurred on a particular print job, such as job aborted, invalid service name, or incorrect password (for passworded services).
53 CHAPTER 7: UNIX/RTEL Host Setup In addition, verify that the service is available. Issue the server command SHOW SERVICE serv_name CHARACTERISTICS. The service port should be the port the printer is physically connected to and the service rating should be non-zero.

60 ETHERNET PRINT SER VER Appendix D: Network Logins Configuring the EPS from the network is rather simple. You can log into the EPS via LAT, TCP/IP, and NetWare, and you will have a command “shell” with which to configure the EPS. The EPS provides utilities to allow you to configure it from AppleTalk and NetWare nodes without logging in.
61 APPENDIX D: Network Logins From LAT devices, the server’s name (EPS_xxxxxx) should appear as a service on LAT-enabled hosts. If you connect to that service, you will be connected at the password prompt. For example: VMS> SET HOS/LAT EPS_45E23A to connect from a VMS LAT host, or Local> CONNECT EPS_45E32A to connect from LAT devices such as other servers.
