Coding width – via “Is it common to print out code on paper?” – Programmers Stack Exchange

I don’t often read code, but when I do, I print it.
For I a very long time, I’ve been formatting code until about 130 characters width and recently remembered out why:
… remember printing in landscape allowed 132 characters.At Uni, I used to regularly print my code on green bar paper…

It got back memories of working on VT102 terminals and Hercules Graphics Cards adapters doing VAX-VMS (FORTRAN and Pascal) and DOS (Turbo Pascal) programming. The VT102 could do 132 columns (the VT52 only 80) and it was no coincidence that most HGC could do 132 columns as well.
Printing was usually on green-bar paper (in Dutch “zebra-papier”) which was 132 columns wide in landscape form on most line printers.

The source of 80 character line width is actually also by IBM: the punch card https://softwareengineering.stackexchange.com/questions/148677/why-is-80-characters-the-standard-limit-for-code-width/148678#148678
