What is the purpose of a braille printer?

Braille printers, also known as embossers, are used to make copies of electronic documents on paper in a format that is readable by blind people. Instead of using ink, braille embossers create raised dots on paper that form braille symbols. Some braille embossers are used to print short documents for home or office use, and others are used to mass-produce copies of braille books and magazines.
