Nowadays, there are huge numbers of old braille documents found in libraries which are getting obsolete and needs reproducing. Unfortunately, they don't have their original alphabetical text so that can't be re-printed by any braille printer unless we have to translate them manually one by one. This research develops braille duplicator system as Institut Teknologi Sepuluh Nopember (ITS) braille printer's additional feature. It works by photographing braille on smartphone, translating it into text, and sending result wirelessly to add-on device installed on braille printer's interface. Translation is done by image processing. Test result shows its accuracy reach 99%. Thus, braille document can be duplicated without needing its original text.
