1. Overview

This Read Me file contains last-minute product information for the Hewlett-Packard Install Network Printer Wizard for Microsoft Windows 95, Microsoft Windows 98, and Microsoft Windows NT.

2. DHCP

If you try to change just the subnet mask on a JetDirect that has been DHCP configured you will get an error message while using the Hewlett-Packard Install Network Printer Wizard. The reasoning behind this is that once a JetDirect has been manually configured it will store the IP address, subnet mask and default gateway statically instead of trying to obtain them dynamically. If we allowed a change to just the subnet mask then the JetDirect would retain a DHCP used IP address past it's lease time. This could cause IP conflicts in the future. For more information on this subject see the JetDirect Manual.

3. DNS

In a DNS environment, the Hewlett-Packard Install Network Printer Wizard will automtically set up the port with the host name rather than the IP address. If you have a DNS environment that allows Host lookup by IP, but not the reverse lookup, the printer will never print a page. We consider this environment to be an invalidDNS environment. To fix the port without changing the DNS environment open up properties on the printer. Switchto the ports tab. Select the port that is in use for that printer. Click Configure Port. Change the host nameto the correct IP address.

4. Suggest IP Address (Autonet)

The algorithm for obtaining the IP address for the "Suggest Settings..." button is derived from the Internet Draft DHC-IPV4-AUTOCONFIG by R. Troll entitled "Automatically Choosing an IP Address in an Ad-Hoc IPv4 Network". The algorithm for generating the IP address is to randomly generate an address in the 169.254.x.x reserved address range. Determine if it is in use on the network. If it is in use generate another address in the range. Repeat until you generate an address that is not in use. This address is not intended for use on the Internet. Microsoft uses a simmilar scheme for determining an IP address on Windows 98 when in an environment that doesn't have a DHCP or bootp server and it is configured to dynamically determine and IP address.

5. Netware Support

1. Supported Versions

The supported versions of Netware are: 3.11, 3.12, 3.2, 4.11, 4.2. For Novell queue creation, you must be logged into a Novell bindery or NDS server using a Novell supplied client requester. See www.novell.com for client updates.

- NDS Multiple Tree Support

The Hewlett-Packard Install Network Printer Wizard only provides support for the NDS tree the user is currently logged into. If a different tree is desired you must quit the application, change your login to the desired tree and rerun the application.

- Netware 5.0 Support

If Netware 5 is configured for IPX, and an IPX connection is being used on the client, the Hewlett-Packard Install Network Printer Wizard can be used to create an NDS print queue. If Netware 5 is configured for TCP/IP and a TCP/IP connection is being used on the client, the Hewlett-Packard Install Network Printer Wizard can be used to create an IP print path. If the client on which the application is being run has an IPX connection to the Netware 5 server, and the client is logged in, an NDS queue server print path will be recommended. If IPX is not in use but TCP/IP is, a TCP/IP print path will be recommended. In order to create NDS queues, an IPX connection with a login must be present.

- No Novell Print Path

The Hewlett-Packard Install Network Printer Wizard relies upon several DLLs that ship with the Novell Client for 95 and NT. The application will look for these DLLs and needed entry points within them. If any of the needed DLLs are missing or if they do not have the needed entry points (perhaps an old version), no Novell print path will be available although any other supported print paths will be. In the event no Novell print path is available when you think one should be, try upgrading your Novell client software to a newer version.

6. Device Discovery

a. Gateway

Discovery performance will be very poor if your client PC does not have a gateway configured. To configure a gateway, choose "Network" in the Control Panel, and then look at properties on the TCP/IP protocol. An input should appear for entering a gateway address. See the online help for a more information on TCP/IP and gateways.

2. Multi-homed Machines

Multi-homed machines are not supported. In this configuration it is not possible to distinguish between multiple devices with the same IP address. A multi-homed machine is a machine with more than one network connection. It is possible for two or more devices to have the same IP address on different networks. A multi-homed machine would see both and you would have no guarantee of configuring the desired unit.

3. 0.0.0.0 IP Addresses

For approximately 5 minutes after being reset, a JetDirect connected printer will have an IP address of "0.0.0.0". After 5 minutes the IP address will change to "192.0.0.192". Attempts to configure a "0.0.0.0" device through an IP print path will fail. You must wait until it has a non-zero IP address before configuring it.

4. Class A Subnet Masks

If the machine running the Hewlett-Packard Install Network Printer Wizard has an IP subnet mask of "255.0.0.0" (which is known as a "Class A" subnet mask), device discovery will suffer a significant performance degradation. To improve discovery performance you must change your subnet mask to a non-Class A subnet mask.

7. Driver Support

1. License Support

Some drivers require the acceptance of a license. If a dialog appears, when installing a driver, asking for the acceptance of a license, you must approve the license before the application will continue. Failure to approve the license will result in the application hanging.

Have Disk Support

In order to support new printers or drivers, the "Have Disk" button can be utilized during driver installation. In order for the "Have Disk" functionality to work, the media must contain an "inf" file (e.g. filename.inf). Some driver updates available on the World Wide Web are in the form of self-extracting archives and are not in a format that "Have Disk" can utilize.

HP Driver Updates

Hewlett-Packard driver updates can be found on the World Wide Web at:

IPX Port Monitor and Data Corruption

Some printers may experience data corruption when used with the Hewlett-Packard IPX Port monitor under Windows NT. These errors may be corrected either by installing an appropriate hot fix for NT or by installing Service Patch 4 from Microsoft

. Printer Names

When naming a printer within the Hewlett-Packard Install Network Printer Wizard you must enter a name in English that conforms to the Microsoft Printer Naming rules (i.e. what would be accepted in the Microsoft Add Printer Wizard). If a language localized name is required, first name the printer in English and finish the install. Then open the printer folder from the Control Panel and highlight the desired printer by clicking on it and select "Rename" from the File menu. Now the printer can be renamed with a localized name.
