  I have seen "side-effects" of sending something other than 360dpi, but
these types of artifacts are not detectable when printing photographic
images.  Whether or not the "printer resampling adds artifacts", is
debatable ... more importantly, it is not what you describe as "inkjetty" in
your previous post.  Once you have remedied that problem, you can return to
making an effort for "best technique" and 360dpi, and see if these
resampling efforts actually help (but I suspect side-effects of resampling
with PS to be no better than using the printer's algorithm ... as if you
should consider 360dpi from the get-go and avoid any resampling ... but
that's difficult in practice)

  I suspect your "inkjetty" problem is "grain aliasing" acquired with your
scanner.  Vuescan's "grain removal" will help, but at some cost of softening
your image.  Still, Vuescan's GR is better than anything you can accomplish
with Photoshop ... try it, and at least use it to figure out what is causing
your "inkjetty-ness".

  I always find grain to be the worst problem in regions of sky ... clouds
and all.  One trick I use is to mask the foreground detail and apply "motion
blur" (e.g., 13pixels: 4 degrees, and 9pixels: -5 degrees) to the sky for
removal the artifacts of film grain.
