How do I install an HP Laserjet 4000 printer

I've inherited an HP LaserJet 4000 printer which I know is in good working order and was working over a network at work until last week.

I want to be able to print to it wirelessly at home from two laptops and had assumed that if I plugged the printer into my wireless router using an RJ45 cable, Windows 7 would do its magic with the printer wizard and let me print to it directly.

Could anyone tell my what I need to do.

I'm running Windows 7 - 32 bit.
I have a cabled connection between the printer and the router.
Windows can't detect the printer.
I've temporarily disabled the firewall (Zonealarm)

Thanks

Thanks for the help Poorman. Much appreciated.

On the back of your advice I searched the net to find out how to reset the IP address on the printer and found the following in case that's of use to anyone else..

Working through the options, I was easily able to set the printer to dynamically allocate an IP address and the Windows 7 add network printer wizard did the rest.
