Default Re: Digital hard copy?

There was a time when all computer programs for nuclear power stations had to be supplied on punched paper tape, as that was the only storage mechanism known to be readable over many decades (given proper storage). Magnetic storage was accepted in addition, for convenience.

One could imagine that a modern method would involve some sort of bar code printed on paper tape, as this could give greater bit density.
