Braille Printers Also known as Braille Embosser they create text as Braille. Using special translation software it will print a document by punching dots onto special Braille paper, which is thicker and more costly than normal paper. This software allows visually impaired and blind people to have hard copies of text but in a language they can understand if they are familiar with Braille.
