Changing the IP Address manually for Laserjet 2100TN

[Coronaviridae]

Hi there--

We recently updated all the IP addresses for our LAN to facilitate the set-up of a VPN. Due to problems arising from DHCP address assignment in the past, we maintain addresses manually on the network. Unfortunately this has led to a problem where our old 2100TN is now unreachable on the ethernet network and we are unable to change its IP address; ordinarily this would not be an issue as the Macintosh computers on the network can still find it via AppleTalk, but the PCs are unable to locate it. I tried running HP's network set-up wizard from a PC connected to the network the printer's on and was unable to locate it even when I searched for the printer's hardware address; this was also the case when I connected directly to the printer with an ethernet cable.

Is there any other way to reconfigure the printer's network settings without potentially disrupting our entire network again? Help would be greatly appreciated. 🙂

Have you tried changing the printer's IP address manually from one of the Macs that can see it?

I include a copy of a reply on a related subject, from the person on this forum whose user name is IronBadger. Some of it may be helpful. Thank him if it helps.

IronBadger's helpful and informed post begins here:

Since Apple removed AppleTalk from 10.6 it may be slightly more complicated to connect your 5100.  But it is possible.

 

A lot depends on what your internet connection is.  Do you use wired or wireless ethernet to connect to the internet?  If you are using a wired connection your 5100 will need an IP address that matches your Macintosh.  This will involve using the printers control panel to manually assign a TCP/IP address that is in the same range as your Macintosh. Wireless instructions below.

 

If the Mac has an IP address of 169.254.12.54 and subnet mask as 255.255.0.0, change the IP of the printer to 169.254.12.55, change the subnet mask to 255.255.0.0 and change the Gateway to match what is shown on  t he Mac.  If your Macintosh gets an IP address directly from your ISP (via DHCP) you may be required to obtain an additional address for the printer.

If you are using wireless (airport) to connect to the internet and just have the printer connected to the Macintosh with wired ethernet the information below should help you get connected.

 

I have copied a document below that discusses putting the printer on the same network as the Macintosh.

 

These are the instructions for manually configuring the IP Address on a Macintosh to match an AutoIP generated IP address on a printer.

 

When some HP LaserJet printers are connected to a network but there is not a DHCP or BOOTP server available it will generate an IP address in the AutoIP range of 169.254.x.x where the last two numbers are derived from the printer's MAC address.

 

To verify the printer's IP address print a configuration page.

 

If the printer configuration shows the IP in the Range of 169.254.X.X then the printer has typically self configured an IP address.

If the Macintosh is either not connected to the internet or is not using Built-in Ethernet for internet connectivity the IP address on the Macintosh can be configured to connect to the printer on a local network.

 

This can also be used to temporarily connect to a printer with no control panel and change its IP address.

 

Check the IP address on one of the computers on the local network:

1. Click on the Apple menu.

2. Select System Preferences.

3. Select the Network System Preference.

4. Click the TCP/IP tab, click the Configure IPv4 dropdown. and select “Manually.”

5. Change the IP address as mentioned in the following example.

• If the printer has an IP address of 169.254.12.54 and subnet mask as 255.255.0.0, change the IP of the computer to 169.254.12.55, change the subnet mask to 255.255.0.0 and change the Gateway to 0.0.0.0.

 

Connectivity to the printer can be confirmed by:

 

Opening the embedded web server using a browser by typing http://<ip address of printer>.

Setting up a print queue for the printer using Print & Fax System Preference.

Hi,

since years I try to configure my 2100tn on my  home network, but never made it and always gave up... this time i managed to get into the browser config page of the printer but... Some plugin is missing (if I go there on win xp) and on mac it states that macintosh is not supported? 

"Macintosh OS is not supported to run this application."

Is there any solution to change the ip? Its set to some very uncommon one, because it used to be a printer in a big business network...but i would love to keep using it, because its a great printer.+

any ideas?

now i managed through installing jre 7 on the virtual xp machine but...
