A cheaper way to print Braille? - Telegraphsounds something similar to solid
dot braille which RNIB used for printing magazines years ago which they
abandoned. I don't think there were many people who liked it.

A reader suggests a way to print Braille characters more cheaply.
May I use your column to suggest that some enterprising genius develops ink,
which can be used in any cheap printer attached to a PC so that the print, when
exposed to heat, expands and produces simulated embossed Braille characters.
Braille may then be printed for pennies rather than the extortionate cost
associated with dedicated Braille embossing printers, which typically cost
between £4000 and £8000.

What a brilliant idea so get your thinking caps on! To get you started I did
some digging around and came across a US patent dating from 1975
(http://goo.gl/u27EY), for Intumescent toner. This expands when exposed to
heat, so in theory an ordinary laser printer, which uses heat to fix toner
particles to the paper, could do the job in one pass. If anyone knows of an
alternative solution or an economical way to print Braille characters please
let me know and I will pass it on.
