Printing vs Making Holograms

I thought as much ... holo_cyware is clearly talking about a different kind of printer in retrospect. Probably recording an angle at a time, mechanically more complex and it makes full parallax prohibitive. For horizontal parallax only it can probably compete in speed with the per pel method though ... and it has the advantage of being much less patent encumbered since it's a variation on ancient techniques.
Not sure if DLP can be used for pulsed lasers, after all, they get grayscales by time dithering...
Clearly it can't and LCOS probably can't deal with the energy density ... I didn't really take into account using pulse lasers, too expensive for my blood. Comes from my amateur way of thinking of development time as free and material cost as the only factor I guess :)

PS. sorry for going off topic.
