I have icing sheets from Icing Images and am using the iPrint software from their website. I read about people having success with using only part of an icing sheet, but can't figure out how to set up my circle layout and only have three, for example, of the circles with a graphic inside of them. Is this possible?

When I insert my logo into only the first three circles and then go to the print preview, the program has filled all 15 circles with the same image and prints a full sheet of 15 circles. I did not click the "Apply to all" button, so I'm not sure why it fills them. I did a test print on regular paper, so as not to waste the icing sheet, but want to get this figured out before printing a real one.

Does anyone know if this is possible? If so, can you give me some pointers?
