Could that be a 5510 "E"? I cannot find a 5510d printer on hp's site. Regardless, HP network printers are not like normal network printers. You still have to install the software. You cannot just punch in the IP address. Doing this just usually takes you to a status page about the printer, its network config, its estimated ink levels, etc. Go here http://h10025.www1.h...582/loc:0&cc=us
Click where it says software & driver downloads. Pick the OS you are currently using. When it gives you the option go under drivers, then download the full feature software and driver. After that downloads, install it, and when that completes and you restart you should be able to print.
