It is the first reply I had, which I find a bit strange: does most development for paralletl scanners rely on them working with a parallel-to-USB connector (and then using UsbSnoop)? I'll try that initially too, but I am afraid that the ALPS scan software may not work at all, hence my looking at direct parallel options. At the moment I lack a Win95 or Win98 VM to try this on, but I'll keep your kind offer in mind. Many thanks once again, Gernot Hassenpflug
