I was around "at that point", and there were a bewildering number of printer types, including daisy wheels and things that were basically converted typewriters, either of which could have produced output like that. Some daisy wheel drivers would vary the spacing to "kern" the letters, but some wouldn't. If they didn't, what you got looked basically exactly like what you'd get on a typewriter.
