Photosmart B110 has IP address and is connected, but my laptop doesn't find it

[Laleh]

My Photosmart has been working just fine and now suddenly it has stopped working.  It shows that it is connected to the network, but when I enter its IP address to try to get my PC to recognise it, it won't connect to that IP address. I have uninstalled the driver and tried to reinstall a new download of the driver but doesn't work becaue it can't detect the printer.

I have tried pinging the printer IP address from my computer, and it times out.  What should I do?

When you compare the IP from the printer and the one from the laptop, are they almost the same?

xxx.xxx.xxx.100

xxx.xxx.xxx.102

The x numbers should match and the last three digits should be within a few numbers of each other.  If not the printer might be connected to a different network than the computer.

Another problem can be a firewall preventing the laptop from seeing the printer.
