Carbonless forms are a type of custom-coated inkjet printer that allows you to make instant copies as soon as your document has been written. This saves time and money, especially when compared with the traditional process where one must wait for printing before they can create more copies from their original version; however, it does not allow post-printed papers so be sure there's enough room on these forms if needed or else some errors may occur during mailing. 

8.5  x 11" size allows more space than most other sizes and can be used at first not only because it's less expensive and versatile too!
