The Braille Express 150, that is built in a durable, transportable case, embosses two-sided, interpoint Braille at a speed of 150 characters per second. The Braille Express 150 has a 500-page memory that can hold your largest Braille jobs. In production, we estimate that a Braille Express 150, used for five hours a day, can produce about 500,000 Braille pages in a year.
