Presumably done by an electronic typewriter? AFAIK they would buffer a line (or more?) of whatever you're writing, and when you hit enter, everything will be printed/punched out. I'm guessing it has a setting to justify, and it does that by adjusting the gaps between letters.

Indeed. With a font that's monospaced (or close) that kind of justification isn't hard. I had a typewriter that could do that. (I don't remember how it handled hyphenation)

Those typewriters were an odd generation, technology between PCs and the older but more expensive IBM Selectric typewriters. I cannot remember if mine was called a "word processor" (I don't think so) but it certainly had a little 8-bit computer in there.
