Certainly a prolific problem.  I prefer to say SPI as it relates to the
scanner, PPI is what you output TO the printer driver, and DPI is what the
printer prints.

Optical resolution...agreed.  Some scanners list interpolated resolutions as
their maximum resolution...

I have no idea what you mean by that...would you please elaborate?
