A preprint is an unrefereed draft. A postprint is a peer-reviewed,
revised, accepted draft, anything from the authorès final accepted
draft to the publisher's PDF:

Not only is it not necessary to deposit the publisher's PDF, it is not
even useful; there are far more publisher restrictions and embargoes on
the publisher's PDF than on the author's final draft:

What all the major mandates require authors to deposit is the author's
peer-reviewed, revised, accepted draft, not the publisher's proprietary
version.
