I can see that with tty, given the resolution it has to work with. But what drivers are you using for troff/groff? I’m formatting paperbacks and haven’t run into any issues so far. Printers also have some slop. Run the same page through twice and you’ll see what I mean. If you’re trying to position something on letterhead with very little margin for error, I could see where that would be a problem as well. — Larry
