Digital BW, The Print

Jerry: I find that if I scan at a resolution that give me something
around 360 ppi in the desired print size, never resample in PS, and
just send whatever resolution I have to my 1280, I get prints as good
as they ever get.

This means scanning at less than my scanners max resolution, faster
scans, smaller files, faster workflow, and the same maximum print
quality.
