Make and model of the printer? Computer operating systems that are trying to connect to the printer?
It's not quite clear how the computer is installed and for whom it doesn't work.. If the printer is installed on a local computer, then there's no reason why it shouldn't work from that computer.. But if it's installed on a local computer and you're trying to print to a shared, networked computer, then that's different.. Are you trying to print from YOUR computer to your neighbor's networked printer? Please be specific.
Occasionally, I have found the need to reset "sharing" on the local computer where the printer is installed. Try disabling sharing, then re-enabling the "sharing" of the printer..
On the other hand, if the printer is installed on the network as an IP address type install, then uninstall and remove the printer from the computer's printer lineup, and reinstall it again.
If there are both XP and Vista/Windows 7 computers on the network, be sure to install LLTD on the XP computer.. See the link below:

Hope this helps and let us know more.

My neighbor changed her SNID and PassPhrase on her network so now her printer doesn't work - I added the printer as the default but the network doesn't recognize it - I added the port and the network doesn't recognize it - I tried running the set up wizard from the HP support site and it wouldn't run so I tried to run the diagnostic software - ugh - Anyway - How do I create a manual communication from the printer to the router - I'm sure the entire communication problem is from the initial change in the snid and passphrase but I can't find a path to change the configuration data - I don't have a set up cd or anything either and don't see any type of printer settings in the router log in site -
