First, what is with the all bold? That is a bit over the top...

Your questions are very broad and seem to demonstrate you don't exactly know what you are asking about so you may not even be asking the right questions.

A backdrop refers to something placed behind your subject like seamless paper, bed sheet or a specialized drop sheet so your questions related to printing and how they related to digital photography seem a little out of place. Can you explain further what you are getting at?

Backdrops aren't specific to digital photography. They are usually made from rolls of paper, or sheets of muslin, canvas, or vinyl. They may be plain, patterned, or painted. Chroma key backdrops (either green or blue) are used when you want to replace the background in post processing with some other background.

What is your real question?
