Images aren't made out of dots. It's made out of pixels. 300 pixels per
inch is substantially different than 1440 dots per inch. A dot has fixed
density (either 0% or 100%) and a pixel has a range of density (levels).
Pixels implies continuous tone, and it takes a whole lot more dots (than
pixels) in order to get something that mimics continuous tone.

So comparing 300ppi to 1440dpi, 300ppi definitely has more information in
it.
