I hear you. I recently (as in the last couple of years) upgraded my personal
style guide to allow 96 character long lines. Note that 96 = 64 + 32 so it's
kind of a round number. I choose that value because it makes formatting
source code easier (less "unnecessary" wrapping) and because one can still
print 96 character long lines in a reasonable font on 8.5 x 11 inch paper
without truncation. I don't print my code very often but once in a while I do
for special purposes and it's nice to know that it's going to look okay in
that case.

That said, with Ada I'm seriously considering extending my allowed lines to
128 characters. Between long, fully spelled out names and avoidance of 'use'
statements Ada source lines can get pretty long!

I have long used 130-character lines. That prints legibly in landscape mode.

Tried that. My problem was that I found out that if I tried to mark a
line of source with a highlighter, the highlighting didn't move when I
scrolled the text. Plus it was kind of nasty trying to clean the ink
off my monitor screen. :) :) :)

Just kidding. (Insert old joke with punchline "there's whiteout all
over your screen" here.) But while I think some people are able to
cope without printouts, others sometimes need to have that piece of
paper to look at. Don't ask me why.

I recall a study that determined that people found more errors in code when
examining it on paper than on screen.

Lineprinters had 132 columns as I remember.
