Digital BW, The Print

I can't tell neither who nor where, but I remember someone stating that
sending files with a dpi number over 360 (or some other threshold) to the
printer is a waste of time, since the printer's driver (at least Epson own
driver, don't know about Piezo) is going to discard anyway the
extra-information (i.e., it's downsampling the file). Therefore, apart from
efficiency issues (sending smaller files), it's better to downsample in
Photoshop, that has a better algorithm.
Can someone confirm this, or is it yet another digital legend?

I think you are probably right on all counts. It depends what driver you
are printing through but my point is that the extra step to downsample to
360 dpi is at best unnecessary. 

However it probably doesn't have any impact on image quality either way.
Re dpi, in tests I *thought* I could see some marginal improvements in
image quality through the piezo drivers beyond 360 dpi but frankly I
wouldn't be remotely confident about picking the higher rez images
blindfold.
