Congrats on getting your printer
I buy my supplies from Kopykake too.
You'll need the 6000-SET for edible inks.

Frosting sheets

The frosting sheets shown above are the largest you can use (7.5"x10"). I don't buy the shaped ones (circles, hearts, etc) because you pay the same but get less. You can cut shapes out if you need them and use the leftover pieces for other projects.
Optional items:
