If you print 720 dpi, you will only get 1 pixel vertically since most of these printers only print 720 dpi vertically. So each pixel will be represented by a grid thats 2 x 1 on a 1270, or 4 x 1 dot grid for the 1280 (2880 x 720). For the Epson 2200, at 2800 x 1440, your dot grid is 4 x 2. It can't lay down enough color combinations to dither the apparent continuous tones needed to make it look like a photo. What most likely happens is that if you print a 720 DPI image to the Epson print driver, it probably resamples the image so that it will have enough ink dots per inch to print each pixel.
