1. Depends what setting it's on; most default to "good quality" which uses more ink than is necessary anyway. Easiest way is to actually try it.
2. At large sizes it'll be fine but at slightly smaller sizes (10pt and below) it'll be nasty. Then again 10pt laser print doesn't always copy *that* well either.
3. On a CRT monitor, definitely that's the case.
But on an LCD screen I'm not so sure that is true. A screen that is all black versus a screen that is off does have a visible hue to it on every LCD monitor I've ever seen, so the energy different there is actually going to be pretty minimal. (I'm sure there's a cue there for a Reg Hardware study somewhere)
@ Retrotech
Good old dot matrix printers. Not sure about the life expectancy of the ink ribbon though in terms of the number of pages versus a laser/inkjet printer.
