Annoying Windows 7 Printer Bug

I have an HP Deskjet 6980 Wireless printer. My new computer has Windows 7 x64. After a while the printer would no longer work. In Control Panel it said the printer was offline. Finally I went poking around in Control Panel and found that the Port was configured for a particular IP address. I already knew that my Printer had a built in web server for configuration, so I pointed by browser to that IP address and guess what popped up! My TiVo's configuration Website! My Printer had been assigned a new IP address from DHCP and windows was stuck pointing to the old IP Address. I fixed the problem by randomly typing in IP addresses until I found the printer one, and then changed the port to the correct address. However, this won't stop it from happening again :(
