Eleanor, It is a printing device which uses swell paper. The swell paper is impregnated with little capsules of alcohol. The paper has a diagram, for example printed onto it firstwith black ink. As the paper moves through the printer, it passes past a very bright halogen light source; the heat is attracted to the black image on the paper, the alcohol swells up and produces a tactile image, of a graph for example. It can also be used for Braille printing. The printing costs are quite expensive, so not a cheap source of printing Braille, but very good for long lasting images. Hope that is explained well enough.

DSA are saying that it does not fall within their requirements of supply, and it is the responsibility of the University to provide all class material and handouts in a format I can access. My argument is that this is for my independant work at home and has in effect nothing to do with the University's duty to provide other materials. Can anyone advise please? Thanks, Mike
