Let me re-phrase the question.
Typically, users send 8-bit per channel RGB files (24-bit total) to
Epson printers (2200/7600/9600). It *is* possible to send high-bit
files (16-bit per channel, 48-bit total) and they print very well. The
question is this: Does anyone know if the high-bit files are massaged
down to 8-bit files by either the Epson printers or the Epson drivers?
(or vice versa?) I.e., Is there an advantage to printing high-bit
files to these printers? Epson told me YES, but I'm still dubious, and
I've seen comments scattered around that state that the printers only
use 8-bit/channel data.
Thanks,

At some level, it almost surely uses 16-bit (or higher) precision. If
