Hp eprint picking up different location

Hi, I hope someone can help me with this.

I installed hp eprint on my ipad, and everything was working fine. But for some reason when I went to use it today it thought I was the Hilton Kensington!! It won't find my hp printer and just lists all the other hotels in that network. Very strange!

I tried uninstalling the app and then re installing it but no change.

Any ideas?

Thank you.
