Ted Harris gave the M1 an optical resolution of 2400-2600dpi, which is significantly higher than the 2000dpi optical resolution of the Epsons (my own estimate). I hear conflicting stories of how the M1 compares to the Epsons. Some say it's about the same, but if the M1 really does have 2400-2600dpi optical, then the pictures should look significantly sharper than the Epsons.
