If you’re printing something to be read, take note of how many words appear on each line. Then look in your average novel, and count how many words per line they have.
Human eyes only deal with scanning across about 10-14 words per line. Anything more than that and they loose their place, they get mixed up on the return path and generally get annoyed.
That’s why type setters use columns. It’s not a pretty thing, it’s a loving thing. They just want to make it easier for people to read.
