How do I connect a Canon Pixma MG5420 printer to new iPad
I have volunteered to help my 90 year old aunt setup her new iPad4 and Canon Pixma MG5420 printer and an old Airport Express! No computer! I got the iPad setup on the network, The printer keeps asking for me to press the WPA button on the router, the AirPort Express doesn't have any buttons. I found a manual way of setting up the printer, I set it to the same Apple Network ssid the iPad is set to, but the printer is now asking for the WEP hex Key Code (5, 10 or 26 digits i think it was). This Key Code was not displayed during the iPad setup, how do i get this Key Code?
Thanks!
