Actually there are a few things you should do. After you put in your edible inks, go in to the printer properties. Go in to your printer properties, Select the maintenance tab. Under "custom settings" Click on Prevent paper abrasion. This will open the rollers a bit for you. Every time you print it will pop up stating that you have it set this way and you can click "ok" to go beyond this. Also, set your paper settings to "matte" photo paper.
You can use any software program you like to design your image. But when you go to print, there is a printing program that we have. You should have received a document giving you the printing program directions and where to get it for free. If you did not, just email me directly and we will forward it to you.
