Should have asked this 20 years ago when everyone
remembered (well, those of you who'd been weaned by
that point, anyway...).
200, 556, 800, 1600bpi: bpi, bits per inch. I understand this one.
3200 cpi: is this characters-per-inch?
6250 fcpi: what, "framed" characters per inch?
One certainly can't figure this out merely by looking
at the capacities of the various modes...
Mostly just a curiosity, nothing really hinges on this...
