Seems his prices of embossers are as up to date as his knowledge of
the technology.

sounds 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 <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.
