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

a. 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.
b. 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.
c. 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.
 
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.

b. 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.

c. 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.

d. 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

a. 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.

b. 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.

c. HP Driver Updates
   Hewlett-Packard driver updates can be found on the World Wide Web at: http://www.hp.com/cposupport/eschome.html
   This URL is subject to change.

d. 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
 
8. 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.
