Sure, see POD is a term loosely used here for Ingram but technically its basically Print on Demand. Repro does both Print on Demand /Book on Demand + Short Run Digital ( Which is basically an alternative to offset printing for printing books with short run (Less than 1000 copies usually) instead of going for the costlier Offset Printing Model.
So when it comes to Ingram, yes repro is doing it but POD as a term is used for normal digital printing for books of other publishers also where the competition is immense , where prices are given per page
