I have a Canon Pixma MG5320, which is probably a basic model compared to what others have but I'm very pleased with it. I especially like that it is wireless as my laptop is often not in the same area as my printer (weird to have a printer live in my kitchen).
I use KopyKake icing sheets and ink and their complimentary program which helps with layout.
I'm very pleased with what I've been able to achieve with my edible printer
