Luca,

The DPI setting in the driver for the R2400 is going to affect print
quality (or "not", depending on whether you'll actually be able to "see"
the difference in output quality between Best Photo and RPM on whatever
paper you're printing on.)

Your mileage will vary. Personally, I've skipped printing with RPM (on the
R800 that I'm using as one of my test printers) just to keep my print times
down.

Whatever quality difference you may or may not see here will be in from
the higher resolution output of the printer, however; it won't have anything
directly to do with whatever profiles you end up building.

With that said, yes, if you're going to print on a given paper type and
want the best possible profile, you will want to use PFP to print its
target(s) at each resolution and to build a separate profile, for each
resolution, for the same paper. There are almost certainly going to be subtle
differences in the way that the target patches print, based on the resolution
you print the target at and the same resolution you would be using the
PF profile with when you print.

The same comment applies if you're going to drop down to even lower resolution,
in case you want to build profiles specifically for lower res prints.
