Alrighty, then: if the differences in output between 1440 and 2880 are so
slight, why are these settings available? Assuming all other parameters are
equal, will prints made at 1440 be noticeably different from 2880? (To me they
are, but only in extremely rare circumstances.)
Surely the good folks at Epson are not so wickedly prescient that they baked
these options into their driver to deliberately provoke Andrew and Ben into
their highly embarrassing flame war. (You guys realize how small these ad
hominem attacks make you look, yes?) Ditto for the other options.
TIA for your help (and please, don’t stack me because I am ignorant.)
