Uses ticker tape as a paper supply. Handy for transcribing
conversations in Morse code, recording the EKGs of dead
people, and literally dozens of other "uses".

You mean it just printed dots? |

This was also called the telegraph printer. |

[IanTindale] - I remember when the holes in the paper for the tractor feed would tear, yeilding a one-line report. Did you have a slipped head-drive belt as well? |

This is how Morse code originally worked. A solenoid raised and lowered a pen that made contact with a steadily scrolling strip of tape. Then people realised that experienced operators could decode the message without actually looking at the tape, so they took it out completely, and we ended up where we are today. |

So this is punched tape storage but with ink instead... |

The Hughes Telegraph actually prints out the text of the
message, not the Morse code itself. It's not really the
same thing at all. |

Besides, this idea isn't specifically for a Morse code
printer, just a printer that prints in one dimension. You
could also use it to, say, diagram the shortest path
coplanar to the paper between the midpoints of the two
line segments described by the intersection of the paper
and two parallel lines coplanar with the paper and
running perpendicular to the direction of travel of the
print head relative to the paper. Try doing THAT with a
telegraph printer. |
