I used to get them printed at New York Cake but they no longer offer that service.
AIf your supermarket has a bakery you can ask. I needed an image once on a cake but I did not have an edible printer ( still don't). The cake Gods led me to inquire at my supermarket. The baker there was super nice. She told me to just bring in the image and she would scan/print it on the edible paper. A bit pricey though- $8.00 for images on an 8.5 x 11 inches page. Good luck:)
Great - thank you. I'll try that.
