WWF, a new PDF that you can’t print.
Huge junk of trees got cut down every day, but from what I know, every one tree that got chopped, another two were planted back. What on earth is WWF thinking when they made this? A PDF file format that cannot print? That’s just adding a few more steps to EXPORT + PRINT. Obviously the people never knew the “Print Screen” key on the top right too. But it’s still a gooding cause, at least a good try.
“The WWF format is a PDF that cannot be printed out. It’s a simple way to avoid unnecessary printing. So here’s your chance to save trees and help the environment. Decide for yourself which documents don’t need printing out – then simply save them as WWF.”
At least this is a good preventive measure to stop some people from simply printing every email that they received, even when some of them are one-liner asking about a certain project’s status. For now, it’s only readable on a Mac, which means that WWF files also cannot be printed from a PC. That’s great news. Also might stop some students from printing every single reading material from the lecturers and professors. But then since hackers are mostly youngsters, I won’t bet on that.
