"Pre-print" implies it's headed to be "printed" by a publisher. That is, the paper has already been accepted for publication by a peer-reviewed publisher, and it's just being posted early for wider and faster dissemination or to stake a claim of priority.
Otherwise, the document is a self-published manuscript, which doesn't carry the authority implied by "publication" or even "pre-print".
