Need to attach printer to NEW wi-fi but can't get it off old wi-fi

[medmondsr]

i just bought a macbook, airport, and hp photosmart c4780. Stupidly set up the printer before I set up the airport. So now the printer is attached to my old linksys wi-fi that doesn't exists anymore and wont recognize the new airport router when i perform HP Setup Assistant. 

again, im running a mac (snow leopard if it matters)  i would like to print wirelessly from my new wi-fi network.

does anyone know how to disconnect the printer from a network?

thank you very much

For Snow Leopard the printer drivers are built into the OS.  Do this:

1. Get the Airport set up and your computer connected to it so you can access the internet.

2. Unplug the printer from the wall, wait a minute, then plug it back in and re-start it.

3. Go to System Preferences, Print & Fax and add a printer (delete the printer first if it appears in the list by selecting it and hitting the minus sign).

4. You should see your printer on the network, select it and click Add.

Let me know if this works, please.

All of HP's newest wireless printers have WPS (Wi-Fi Protected Setup) in them.  This allows a very simple method to connect your wireless HP printer to your Wi-Fi network.

It's very simple:  Start the WPS Pushbutton method (under the printer's wireless menu) on the printer and then press the WPS button on your wireless-router.

Since Apple wireless-routers do not have an external WPS button, here's what you do:

1. open the Apple Airport Utility
2. select your wireless router
3. select Manual Setup
4. select Add Wireless Clients ... from the Base Station menu
5. Select First Attempt then press Continue.

You have to start the Apple Add Wireless Client process within two minutes of starting the printer's WPS pushbutton method.  Actually, order doesn't matter ... you can start the Add Wireless Clients process on the the Apple router first then start the printer's WPS pushbutton method.

i could not find the Add Wireless Clients button under the Base station menu on the airport utility. i unplugged the printer and plugged it back in, then deleted it from the Printer & Fax menu  but couldn't find it when I tried to add it back again.

Nevermind. Im not sure what I did. But I unplugged the Printer completely and after a few different tries it appeared on my list of available printers. After that I did the same thing on all of the other computers and it appeared with no problems on the XP and Vista systems.   

Thank you very much
