Title: Do not need
Review: I don't own this so I can't comment on it's functionality but you do not need this. As someone else mentioned already, Canon says the Pixma MP470 does not support other adapters (I even contacted their support department) but it is not true. After reading the aforementioned review, I tried my own Bluetooth adapter (paid $8.99) and it worked fine--although, depending on your adapter, you may need a USB extender like I did.
Is this product review negative?
