Hi, 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 you use HTH Gerhard
