A point I try to make often; That what you see on the screen can be captured in whatever way one wants to view it, even if it is on paper. (Rarely ever my choice.) I assume you meant that the 3D annotation on a CAD model can be "printed" along with the other various design data that belongs to the model. AHHH. The other design data. Now we get into configuration management, another one of my favorite discussions. But, another time.

When you say there is only "one brand that does it"; Do you mean one brand of printer or one brand of software? Frankly, I find that hard to believe so maybe I missed something.
