Since this is a zink printer all zink photo paper made for Canon, Polaroid, and HP can be used. You will likely need to save at least one of the blue card from this brand of photo paper.
I have a Polaroid snap and I use canon ivy and hp sprocket printer papers if I see a good deal. Polaroid has the bulk pack which is a good price.
The only downside to these app printers is the required app to use it with. We all know apps have bugs and eventually will not be updated or even supported when new OS are update or new phones are introduced.
Very useful information - thanks!
