But they were very similar to the barrel line-printers on the 326s at Charles House, Kensington CC. The process involved fitting a rubber sheet about 0.5mm thick between the hammer array and paper, and removing the ink ribbon, so that printing dots in Braille code would leave raised dots on the paper. Then adjusting the hammer force carefully so they didn&#8217;t actually puncture the paper.<br>I used the same technique a few years later, on a much later timesharing mainframe (a DECSystem-10) because a completely blind little boy joined the Cub Scout pack where my wife was a leader. So we found software to translate the text of some of the Cub Scout Handbook into Braille, and I made a Braille-print kit for our lineprinter and &#8216;borrowed&#8217; it for a few evenings.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>John Paschoud\u00a0on printing Braille programmes.
