Epson printers give their most effective and efficient results with an image input resolution of 360 or 720 pixels per inch ("native resolution"), depending on the model. Desktop printers, like the R2400 use 720, and large format printers like the 7800 use 360, that said, you're likely to never see any quality difference on the R2400 by using 720 instead of 360. From this input resolution, one can make prints at a variety of PRINTER output resolutions, i.e. 360 x 360 dpi, 360 x 720 dpi, 720 x 720 dpi, 720 x 1440 dpi, 1440 x 1440 dpi and 1440 x 2880 dpi. Increasing the input resolution to an Epson printer does NOT significantly increase output quality. This makes the Epson very efficient and significantly decreases image file sizes and printer spooling times.
HP, Canon, Lexmark and other printers typically have a "native resolution" of 300 ppi. ....
