A device can be an add-on to existing printers in order to assist the visually impaired. An electronic device is placed over the indicator lamps that would act as a transducer for the optical output to transform it into a signal readily interpretable by someone who is visually impaired. In one embodiment, a thin plastic overlay is molded in the same shape as the printer interface. Inside the overlay would be photodetectors positioned over the existing LED displays. These photodetectors would relay the visual light information to a processor which would convert it to an audio signal. A piezoelectric beeper or voice chip would produce the appropriate audio cue to the user.
