Digital BW, The Print

RPM will take at least twice as long (or even longer?) as the next
best setting. I'm not sure because I only tried it once, decided the
very subtle differences between RPM and Best Photo were not worth it
(and not indisputably "better" with RPM), and never tried it again.
Try some side-by-side comparisons and see for yourself. The print
quality you get for your buck w/ the R220 is astounding, but you have
to expect some tradeoffs in other areas.
