Yes, for most printing 300dpi output resolution is good enough, for example the
Kodak 8650 dye-sub printer. But the Fuji Pictrography output at 400dpi continue
tone that need the same input to get the best result. For ink-jet prints,
200dpi is good enough for normal photo, but if it containing some texts you may
need higher resoultion to get the sharp text output. If you have lots of memory
and computer power, 300dpi is recommended.
