Use Your Printer To Decorate Cake
There are so many things you can actually do with your printer aside from the usual tasks. You can try to print miniature images and place it on top of muffins and other bread, hard candy, gingerbread houses, cookies, cheesecake, pies and gelatin. The concept of something coming out of a printer that is edible just seems to defy common logic.

You can use actual photos or meaningful images. You will then need to put a ”base coat”of frosting on your cupcakes. Once you are ready, print the design on edible frosting sheets using edible ink.
First, you will need to find edible paper. These sheets are sold online or in some craft or baking stores. Edible paper is made from rice or potato starch. There are a variety of sizes and shapes that are all safe for your printer and for your belly. Next, you need edible ink. Mostly, it contains food coloring from natural and synthetic materials that don't contain any toxic chemicals.
You can print the outline onto a sheet and then apply it to a cake with frosting. Fill it in using butter cream. The sheet will dissolve and you will only have the outline on the cake. The printer prints the image on a very thin icing sheet mostly made up of cornstarch, sugar and corn syrup. Not all models are compatible with the edible cartridges, Epson and Canon printers were among the first producers of printers that can print using this ink.
There are also refill cartridges and continuous ink systems available, and it is best to make sure you have an adequate supply of ink before beginning the printing process. Unlike regular paper print jobs, you do not want to have to start from scratch if you run out of ink in the middle of the job. It is also suggested you use a separate printer when cake printing, you don't want your family, friends or customers to get ill if there are traces of regular ink in the printer. Regular inks are toxic when ingested. Use air brush cleaning liquid for removing the clogs from the printer head and for removing edible ink from countertops and hands. If you are facing problems aligning the shaped sheets try cutting the shapes out once you print them. If you have ruined a frosting sheet don't throw it away yet. You can store it in a zip lock bag in the freezer and use it later.
So, in the end we can conclude that working with edible ink is rather fun and a tasty way of using printers.
