Braille printers do the actual embossing of Braille onto paper. The first step in converting computer files into a Braille document is to choose the type of Braille. Grade 1 Braille consists of letters, numbers and punctuation marks while grade 2 Braille includes contractions of common combinations of letters and words. To print Grade 2 a Braille translation program must be used to take the computer file, insert the contractions, and format the document for the Braille page.
