is what I use when scanning to TIF or PNG. (Substitute '300' for appropriate scan DPI.)<BR>

you are confusing the dpi of the scan and the dpi of the print. If you<BR>
scan at 150, you should print at 150, if you want the size to match.<BR>
Since the scans as the come from sane likely wont have the dpi<BR>
embedded, you will have to tell someone in your chain of progs what<BR>
the original scan dpi was. try the -density flag to convert.<BR>
