I actually appreciate the fact there's no print function from the Moodle gradebook. I'm afraid my faculty might use it and we'd be back to the days where there all kinds of paper copies of grades floating around, the college would get sued, we'd end up being own by someone else who doesn't appreciate what we do -- its a slippery slope.
We encourage our faculty to export their grades to a Google spreadsheet, very secure, no paper, no emailing copies around, kept forever.
