A Print = A printed physical copy of the piece of art you put up. Kinda like a poster, only smaller. :3 Someone said "Hey, I like this piece of art, I would like to hang it up on my wall" so they requested it.
Someone~... when you submitted your print for the first time, did it go through submission again, but instead of the regular submission, it was a different color and it showed the different sizes with your picture/portrait/etc?
No I don't think so. It just looked like the regular submission thing that pops up when you upload a picture. I never actually submit my pictures as prints cause I never expect anyone to want them >.>
I don't think so. All it said was "blah requested this as a print" then there were the options to "learn more about prints" which I did look at and "submit as a print."
Someone asked you for a print, right? Did they tell you that they will pay you money/points (well, unless you're going to do a commission)?
For example: [link] (this is a picture I took months ago)
Did that help any?
