It will depend on what printer you select. This chart lists Canon and Epson printers that are able to take the edible ink sets: http://www.kopykake.com/documents/PrinterInks-Xref.pdf
Edible ink costs anywhere from $50 to $100 depending on the printer model. Kopykake and Sugarcraft carry them.
24 Frosting sheets from Kopykake (7.5"x10") cost $28. These are also available in other stores and also come in other sizes.
If your printer has been used with regular ink, I suggest getting a new one for edible imaging.
I bought a Canon printer and a variety of icing sheets, plus extra food color cartridges...all together about $250. I have used my printer exactly 5 times in 2 years. Additionally, everytime I used it, I had trouble with the print heads/cartridges. They clog very easily. For me, I think if I had the choice again, I wouldn't purchase the printer. I guess my clients prefer my artwork done by hand. So unless you plan to use your printer all the time, think twice about it before spending the money.
