This must still be somewhat common. I recall e-mails from administration at my previous French lab had in their signature something to the effect of "Think of the environment, do not print this e-mail".
I actually had an example of something similar before my eyes. My advisor's advisor's advisor (...), emeritus, occupied the office next to mine and printed his Fortran code to work on at home. He debugged on paper, then typed it down the next day in the office. His whole career had been at the crossroads of math and computer science, his main contribution algorithms and software, and he did not have a computer at home (says he). This software debugged by hand (and typed with the index fingers) is still used in commercial software!
