I am going to try my hat at this for the first time! My question is, how do you do a larger cake, such as 11 x 15, I only have 1/4 sheets, and it doesn't look like you can get bigger ones!! I guess they wouldn't fit in the printer, anyway if I want to cover a 11 x 15 would I use two 1/4 sheets, not sure how that would work!!

I usually use the 8.5 x 14' icing sheets. On occasion I have also just used the 8.5 x 11' or even the 8" circles and just centered them on the cake.
