But if you scan at a particular resolution, and you want the print to be a
certain size, then you've already determined whether you have less or more
resolution than the printer's native 720ppi resolution.

You can of course change the scan resolution, but in most scanners all that
does is another software resampling, so whether that's good or bad depends
upon the quality of the resampling function. My approach has always been to
scan at the native resolution of the scanner, edit and crop to my heart's
content, and then, if I suspect aliasing might be a problem, upsample in PS
to the next lower submultiple of 720.
