i am scanning at 1200dpi, taking 5x7's, isolating the element(s) in the pic that i want to keep, then printing at 8x10 (usually). yes, i go through a helluva lotta ink! anyway, i'm wondering if 1200dpi is over the top. i want my prints to be as crisp as possible, but i'm wondering if there is an upper threshold for the printer, anyway, thus rendering the larger file for the higher resolution unjustified. anyone know anything about this? my printer is a canons9000.
