Granted, dpi and ppi aren't the same - but print would normally be more like 1200 dpi. Even low en laser printers are 600 dpi. So while you might print a 300 ppi image, you'd probably print it at much higher than 300 dpi. E-ink screens are in a kind of middleground - they certainly have lower contrast and resolution than movable type (depending a bit on paper quality, but compared to say printed books).
