Bummer.

That's cool and I read that but I haven't been able to get it to work.
My parallel port is located at 0x378, which is /dev/lp1 or /dev/par1.

Here's what I attempted in my /etc/sane.d/mustek.conf:
/dev/par1
  option linedistance-fix
  option lineart-fix            # lineart may be faster with this option
off.

I have also tried /dev/lp1 and 0x378 in the place of /dev/par1.

Any hints?

Thanks,
