Moma.org says a print is created not by drawing directly on paper, but through an indirect transfer process. In addition, they say that a print is "made up of ink on paper and existing in multiple examples."
If you go to MOMA's Flash site,
What is a print?, you can check out their explanation of prints and print processes. It's a nice basic discussion and a good insight into how the rest of the world, if given the chance, understands what we do.
