I have tested my 9636T with about 5 different computers, including
a laptop with a 133 MHz pentium. The parallel port on that only
has ECP (with bi-driectional mode), bi-directional, and SPP. It
works on all modes ( as either bi-directional or SPP) but the
speed varies. I use a test scan of part of a color photograph
(total file size ~9MB). It takes 30 sec with an EPP port (CPU
speed is not really relevant unless the computer is doing a lot of
other tasks at the same time) and 1 min 8 sec on the slow laptop.
I am also working on trying to get a usb-to-parallel adapter to
work; the plustek driver code has to be rewritten quite a bit for
this to happen. I am talking to Gerhard about this.
