Hi,
In libksane I try to figure out a suitable scanning resolution by starting with 100 DPI, increasing the DPI with 100 until I reach 300 pixels height or width. The problem with epson2 is that the "pixels_per_line" parameter returned by sane_get_parameters() is always 0. This means that the hard-coded limit of 900 DPI is always reached (or the closest one).
