Alright so I have a Canon mp495 printer. The printer supports Wi-Fi printing. A while back I setup the printer and it has been connected to the network. The light for Wi-Fi is lit up and when I go to the network and click under my name it is listed there. However when my roommate tried to print something via wireless printing nothing happens. He can find it (as far as I know) but when he goes to print it just says connecting and then gets some sort of error. Ideas as to what is wrong?
