[nfbcs] [Nfb-rdcomm] dot matrix printer

[Don Bomer (Tex)]

Hi Gary and all,

I used to repair dot matrix printers and I can assure you that even the 
commercial Centronix printers that I worked on were incapable of printing 
Braille.

You have three strikes against you:
     1.  The print head pins are a fraction of the size of a Braille dot;
     2.  They have insufficient mass and velocity;
     3.  And the platen (rubber roller) is too hard to allow them to make a 
physical impression on the paper.

Warm regards,

Don...
