Will my stubhub tickets scan?

I just bought two general admisson seats via stubhub for a concert in
a few months. The tickets came very fast (2-3 days after I placed the
order), but they came on paper (but they look like legit paper tickets
from ticketmaster that allot of ppl take to concerts).

I know some ppl have had good experiances while other ppl have had bad
ones with stubhub and in my case, will the tickets scan? Because isnt
there a possibility the seller can just be reselling the same tickets
over and over again since their reprintable?
