2 Installation 2 Installation This section describes how to install NDPS Gateway, which is composed of different parts. The gateway component provides NDPS service to NDPS clients for non-NDPS printers. The control snap-in utility manages the Printer Agents. Additionally, the configuration utility allows you to configure the NDPS Printer Agents. 2.1 Installing NDPS The NDPS Gateway is added to the Novell NDPS. Therefore, the first step is to install NDPS. 1. When installing NetWare 5.x or 6.
2 Installation 2.2 Installing NDPS Gateway NDPS Gateway will be installed onto a NetWare server from Windows. Note • Before installation, be sure that you are connected to the NetWare server onto which NDPS Gateway will be installed, or that you are logged on with administrator privileges. • Before upgrading NDPS Gateway to a newer version, perform the following two operations. ⋅ Quit NDPS Gateway. ⋅ Then, quit NWADMIN32.
2 Installation • Authenticated NetWare Servers: A list of NetWare servers that are logged in is displayed. • Unauthenticated NetWare Servers: A list of NetWare servers that are connected but not logged in is displayed. 4. From either the “Authenticated NetWare Servers” or the “Unauthenticated NetWare Servers” list, select the server where NDPS Gateway will be installed. 5. To change the installation location to a folder other than that shown in “Destination Folder”, click the [Browse] button.
3 Printer Agent Configuration 3 Printer Agent Configuration Each NetWare printer is represented by an NDPS (Novell Distributed Print Services) Printer Agent. The NDPS client submits a print job to the NDPS Printer Agent. The NDPS PSM (Print Service Manager) passes the job to the gateway, which submits the job to the NetWare printer for printing. In an NDPS environment, users can configure a device as a Public Access Printer or as a Controlled Access Printer.
3 Printer Agent Configuration Controlled Access Printer A Controlled Access Printer enables you to assign NDS privileges for controlling which users can see, use, and manage this device. To configure a Controlled Access Printer, you can simply create an NDPS printer object to represent the device. The newly created NDPS printer object will appear in the NWADMIN utility’s NDS browser. As with other NDS objects, a Controlled Access Printer offers a full range of security options.
3 Printer Agent Configuration 2. Select “Printer Agent List” from the column at the right, and then click the [New] button to create the Printer Agent. The Create Printer Agent dialog appears. (This dialog is the same as that displayed when creating a Controlled Access Printer, as described below.) 3. Enter the Printer Agent name (e.g., PA1) in the “Printer Agent (PA) Name” box. 4. From the list, according to the syntax “NDPS_Manager_Name.
3 Printer Agent Configuration 3.1.2 For a Controlled Access Printer 1. From the NetWare Administrator dialog, select the context under which the Printer Agent is created in this NDS container (e.g., “CONTEXT_99”). 2. From the “Object” menu, select “Create”. The New Object dialog appears. 3. Select “NDPS Printer”, and then click the [OK] button. The Create NDPS Printer dialog appears.
3 Printer Agent Configuration 4. Enter the Printer Agent name (e.g., PA1) into the “NDPS Printer Name” box. 5. Select “Create a New Printer Agent” under “Printer Agent Source”, and then click the [Create] button. The Create Printer Agent dialog appears. 6. Enter the Printer Agent name (e.g., PA1) into the “Printer Agent (PA) Name” box. 7. From the list, according to the syntax “NDPS_Manager_Name.Context_Name”, select the NDPS manager started up from the server console. 8.
3 Printer Agent Configuration 3.2 Configuring a Printer Agent When creating either a Public Access Printer or a Controlled Access Printer, the same Create Printer Agent dialog appears. After completing the dialog, the NDPS Gateway dialog appears. A list of device names and their corresponding IP address is displayed in the NDPS Gateway dialog.

7 Troubleshooting 7 Troubleshooting The programs should work properly if the procedures described above are followed. Nevertheless, something unexpected could cause them to fail to operate normally. This chapter explains how to diagnose any problems. 7.1 Troubleshooting the NDPS Printer Configuration Module 7.1.1 Why does the “Authentication failed” message appear? This occurs only with the QMS (Queue Management Services) port handler.
7 Troubleshooting • Device is not in “Ready” mode — After the device is turned on, it needs some time for initialization. Use the “ping” command to verify the current state of the device. 7.2 Troubleshooting the NDPS Printer Gateway Module 7.2.1 Why is an NDPS Printer Agent in the “Not Bound” state? The NDPS Printer Agent cannot be initialized for some reason. Press the [ENTER] key to bring up the screen, and then select “Shutdown Printer”. Next, press [ENTER] again, and then select “Startup Printer”.
7 Troubleshooting 7.2.2 Why is an NDPS Printer Agent in the “Needs Attention” state? The device has uncorrected problems at that time. Press [ENTER] to look at its details screen. Press [ENTER] in the status field to list all that device’s problems that are uncorrected. The state will be reset to idle after all of the problems are cleared. If the Printer Agent remains in the “Needs Attention” state for a long period of time, you should go to investigate the error.
7 Troubleshooting 7.3 Troubleshooting the NDPS Printer Control Snap-In Module 7.3.1 Why is the Novell Printer Control snap-in opened for a Device? It is likely that the “MltgCtrl.pc2” file is not copied to the right directory. Since it was not found, the Novell printer control snap-in was opened by default. Copy “MltgCtrl.pc2” to the “SYS:\PUBLIC\WIN32” directory. 7.3.2 Why can a screen not be opened? This usually occurs when a message box containing a number appears. 7.3.
7 Troubleshooting 7.4 Troubleshooting the NDPS Module 7.4.1 Why does an event not generate the pop-up or log message on the client machine? First, be sure to check the events. Select the Printer Agent in the NDPS Printer Manager, select “Configuration” and select “Notification”. There are different icons for different notification mechanisms. You will see at least two, the log and pop-up. Make sure that the events are properly set for each notification method.
