Installing a Pixma Printer via WiFi

[MJinVA]

Greetings,

After much angst trying to install my printer { making sure I had all of the numbers and models and features correct} I was about to give up and just go buy another cheap printer.  

Then - an epiphany!  

Instead of matching the model & serial numbers, I decided to match the picture instead.  EURIKA!!!  It worked!!!
