You're taking the context of printing even further. I was attempting to point out the reasonably intended scope outlined by the poll. which was meant to include physical printing. By your broadening of the word printing beyond reasonable interpretation, internal/external hard drives, forms of flash memory, monitors, scanners, etc. (why include a computer at all you can print without one using a pen and paper or even etch-a-sketch) would all appear as poll options to be selected; but none of these hold any bearing on the statistic attempted to be measured here. The last 2 options about mixed or not performing printing encompass the good faith meaning behind something like "exporting" to PDF where no contrast (ink, toner or what-have-you) is applied to paper or paper-like substance.
