I didn't follow the thread so far, so some hints might be doubled:
- remove the printer from the chain as this might cause problems
(has also be stated by Plustek)
- make sure to have any ECP mode disabled in BIOS (set the port to
SPP, BiDi or EPP)
- for having access to the parallel port as "normal" user you have to
tweak probably the udev/hotplug settings depending on the distribution
