L.DOIGNON CHARACTER PRINTER , 1880's The printer used Baudot's 5 bit code, using five telephone lines, to receive a signal that could be printed on a strip of paper. It was all driven by an electric motor. On receipt of a start signal the five bit code would latch five solenoids that would enable the mechanism to print a character by turning the wheel and engaging the correct letter. After printing a character the solenoids released ready for the next one. A0234 |
