Introduction to networking your printer

Note: The following information is a guide. It covers the broad outline of networking, and is not intended to give you all the information you need to set up a network. Consult the documentation that came with your computer and operating system. If you have doubts about whether you are able to install a network yourself, we recommend that you consult a professional in the field.
You can use your GCC printer on networks. This section of the manual gives you a brief overview of the process and the costs and benefits. Because networks vary considerably from one site to another, the information in this section is a general guide only.
There are two kinds of networks; peer to peer, where every computer can communicate with any other, and client-server, where one or more computers are dedicated as servers and all the other computers on the network are clients.
Client-server computing is normally complicated and is usually administered by trained network specialists. This is because most client-server software can control up to thousands of users, and many features are provided that are not needed at smaller sites.
This section deals mainly with peer to peer networks as these are easier to set up and administer. Depending on the amount of printing that your organization produces, one printer can support up to 25 users. You can always add additional printers as necessary.

Why should I set up a network?

You can set up a network and reap benefits with only two computers. Benefits include:
• One printer will service both users; therefore you save the cost of another printer.
• Depending on how the network is configured, one user can allow the other access to some, all, or none of the files on the computer, and this access can be read-only or read and write. You save on the inconvenience of transferring files by “SneakerNet” — carrying floppy disks from one computer to the other.
• Other peripherals can be shared. You can copy files or install programs from a CD­ROM drive on another computer. You save the cost of equipping both computers with a full range of peripherals.
• Some networks let you mix Macs and PCs so that both platforms can share the printer.
• Most networks have e-mail. Even in small offices e-mail makes sure that messages get to the person who needs them, rather than being lost in a sea of paper.
1
• Depending on your software, you may have additional benefits like the ability to use one computer to send and receive faxes for every user on the network, or being able to back up files to a central disk or tape drive.

What does setting up a network involve?

You need to install a network card in each computer, and provide cable to connect the computers together. In a bus network, each computer is connected to the next in a line; in a star network, all computers are connected to a device called a hub. The reasons why you would choose a bus or a star network are discussed later.
The cost per computer (the cost of a network card and cabling) starts at under $100. You pay more for ease of installation of the card and for faster networking, though the speed of standard Ethernet is more than adequate for small sites. Hubs start at under $100, and the more expensive models allow you to connect more computers (basic hubs often have only five ports).
Most Macintosh computers have some form of networking built-in. All models have AppleTalk, and more recent models have EtherTalk, Apple’s name for its Ethernet imple­mentation. You can mix AppleTalk and EtherTalk computers on the same network.
AppleTalk’s disadvantage is that it is considerably slower than Ethernet. You could find that users on an AppleTalk network become tired of waiting. You can upgrade many Macs to Ethernet.

Where do I connect the printer?

In most cases, you connect the printer directly to a computer on the network. When other users want to print, the file is sent to the computer with the printer attached and stored temporarily on that computer’s hard drive. Then the file is printed in the background. This means that someone working on the computer attached to the printer can continue work­ing on their own programs while the computer is sending the file to the printer.
Some Macintosh networks allow you to connect the printer directly to the network cable, rather than connecting it to a printer.
If many people are sending large files to the printer the person using the computer attached to the printer may find the computer is slowing down; in most cases this will not be a problem. Some organizations dedicate an older computer to be a print server. This com­puter is not normally used for any other purpose; it must be able to run the operating system of the other computers and have sufficient free hard drive space to hold the files that are being printed.
2
If you decide to use a computer as a print server, you may consider also using it as a fax server if your software allows you to do this. Fax servers take the place of a fax machine;
they are left on continuously, and users have a password-protected area to receive faxes. Fax servers can also send faxes from anyone on the network, and the printer takes the place of the printing part of a fax machine. A fax server needs a modem and a phone line.

What happens when someone turns a computer off?

The network continues to run if a computer is turned off, but the files, printer, and other resources associated with that computer are no longer available to other computers on the network.

What if more than one person wants to print at the same time?

When several people send files to the computer attached to the printer, the first file re­ceived is printed, and the remainder are queued — that is, they are stored in order on the hard drive and printed in order when the printer is free.

What about security?

Once a computer is connected on a network you must do more than lock the door to prevent access to it. Most systems allow you to specify which folders or directories can be shared with other users, and let you name the users and specify that they have the correct password. Computers that print sensitive materials should not print to printers in a public area.
Passwords aren’t usually the first thing on peoples’ minds when a small network is set up, but without proper password protection many unwanted things can happen. These can include malicious e-mail sent under your name, employee snooping of sensitive material, and outsiders sneaking into an office to search the network while the user is out to lunch.
People tend to choose passwords that are easy to remember; unfortunately, these pass­words are also easy to deduce. Names of spouses, children or pets may be known to co­workers. If passwords are too complex people tend to write them down and put them in a desk drawer, which defeats the purpose.
MHALLIFW is an example of a password that cannot be easily guessed, but it seems that could be easily forgotten until you realize that it is the initial letters of the first eight words of the nursery rhyme “Mary had a little lamb.” Initial letters of lines from songs or adver­tising slogans can also be used.
3
Which kind of network layout — bus or star?
When you make network using a bus layout, you use a type of cable called thin Ethernet. This cable and the connectors used with it are called 10BASE-2. You do not need a hub for a bus network, but if the cable is broken at any point some computers will not be able to communicate with the others.
In contrast, a problem with a cable on a star network means that only one computer is affected. The cabling used is called Unshielded Twisted Pair (UTP), and this method is called 10BASE-T. For a simple network, either method will be satisfactory.
In some cases, if your computer comes with a network card, you may be forced to use one system or the other unless you replace the card. Other network cards may have both interfaces.

How will I know if I have enough printers for everyone?

If you do not have enough printers for your needs, your users will tell you. They will complain about having to wait until their jobs appear. In this case, you can add a printer to the network.

NEST : Introduction
NEST (Novell Embedded Software Technology) is code written by Novell and licensed by GCC. It provides NetWare protocols and is configured using standard NetWare utilities. It offers these advantages:
• Your printer does not require a dedicated print server, so it connects directly to the network.
• You can install the printer anywhere you have an Ethernet connection.
• NEST works with GCC’s WebAdmin utility.
This manual shows you how to install and configure your GCC printer to work with your NetWare network. You set up your printer in two steps – the usual NetWare setup, fol­lowed by the GCC specific NEST setup. If any of the computers on your network are creating PostScript jobs using Windows, you will also need to configure them.
The printer’s NEST specific parameters are set up using GCC’s WebAdmin utility. Instruc­tions for accessing and using the WebAdmin utility are located later in this section and in Section 2 of this manual.
If you do not have TCP/IP on your network, you will be unable to use WebAdmin. In that case you will need to use GCC’s NEST Config Tool, which is supplied on this CD.

Setting up your Printer

The instructions in this section are a condensed version of those in the installation guide, and are intended for users experienced in setting up network laser printers. If you have questions about any of the steps in this section, consult that section of the manual.
1. Unpack the printer and install the toner cartridge.
2. Insert paper into the paper tray and insert the paper tray into the printer.
3. Connect a cable from the Ethernet port to the network.
4. Plug the AC power cord into the printer, then plug it into a grounded AC outlet.
5. Switch on the printer.

General NetWare Setup

This section discusses the NetWare utilities you use to set up your printer. This process is the same as setting up any printer, but in a few cases there are specific instructions to configure the NEST options. These are included in the instructions where necessary.
5
The instructions are described first for NetWare 3.12, and then for NetWare 4.1 (beginning on page 1-6). The utilities included in this section are PCONSOLE, NWADMIN, and NETADMIN.

NetWare 3.12 instructions

PCONSOLE

PCONSOLE has two functions: setting up and managing print queues, and setting up and managing print servers. This manual covers the outline of how to set up queues and serv­ers; you must create at least one queue and one print server. For more details consult your NetWare documentation.

Creating a Print Queue

1. Log into the file server as SUPERVISOR (or equivalent).
2. Start the PCONSOLE program (it is located in SYS:PUBLIC).
First you create a print queue.
3. From the menu (shown in figure 1) choose Print Queue Information.
4. Press Ins to add a new item to the list of queues.
5. Type the name of the new queue and press Enter.
Then you add users to the queue.
6. With your new queue selected, press Enter again.
7. Choose Queue Users from the Print Queue Information menu and
press Enter.

13. You must configure the printer as printer zero (0). Press Enter.
14. Type a name for the printer and press Enter.
15. You will see a list of Printer Types (as in figure 2). Your printer must be
defined as Other Remote/Unknown. Select this option from the list.
Finally you assign your queue to your printer.
16. When you have defined your printer, press Esc to return to the Print Server Configuration menu.
17. Choose Queues Serviced by Printer from this menu and press Enter.
18. Assign the queue you just created to the printer (see your NetWare docu­mentation for more details).
19. When you have finished, press Esc to return to the Print Server Con- figuration menu.
You may want to implement this optional item.
20a. Choose Notify List for Printer and press enter.
8
20b. Choose the printer, and then select users that you wish to be notified
when the printer has a problem (see your NetWare documentation for more details).
20c. When you have completed your Notify List, press Esc until you return to
the Print Server Information menu.
When you have made all your changes, you exit PCONSOLE.
21. Press Esc three times to return to the PCONSOLE main menu.
22. Press Esc to save changes and exit PCONSOLE.
This ends the section of this manual devoted to NetWare 3.12. Now continue with the section “NEST-specific Setup” on page 11.

Using GCC tools to remotely configure NEST on your printer

GCC provides two tools to let you remotely configure NEST.
If your network uses TCP/IP, WebAdmin allows you to view and/or change many param­eters of the printer using a World Wide Web browser over an Ethernet network. Please see the WebAdmin section of this manual for information on installation and setup of the WebAdmin utility.
If your network doesn’t use TCP/IP, you can use the NEST Config tool to view and config­ure NEST printers.

Using WebAdmin to set up NEST

The following instructions for setting up NEST with a GCC printer apply to both NetWare
3.12 and 4.X.
All GCC printers on the network that you are intending to use with NEST MUST be accessible using WebAdmin. The following instructions assume you have followed the setup in Section 2 and are able to access the printer using WebAdmin.
First, ensure that NEST is enabled on the printer.
1. Launch your World Wide Web browser and attached to your printer as explained in Section 2.
2. Select (click) NETWORKS from the WebAdmin main menu. The Networks main menu is displayed.
3. If NEST is disabled, use the pull-down menu to enable it and restart your printer.
4. Once the printer is configured with NEST enabled, select the NEST link. The NEST Subjects menu appears.
The NEST Subjects menu displays the available subject items (General, Network, NPRINTER and PSERVER) that may be changed. If you select one of the links on this page, a menu of parameters will be displayed for the subject you have selected.
The following information pertains only to those items that are required to change for NEST printing. If you are installing under NetWare 3.12, continue with the instructions below. If you are installing under NetWare 4.x, skip to the section that deals with this version of NetWare.

NetWare 3.12 setup with WebAdmin

If you are installing under NetWare 3.12, you will need to configure the following items.
