    I am assuming that the Jaz drive itself is a 'standard' SCSI external
    drive and the the Jaz Traveller is a gadget that connects to the
    parallel port and then provides a SCSI connection for the Jaz drive. If
    this is the case, yes, it *should* work with any SCSI device. This
    assumes that Iomega has not done something strange and wonderful.

    The scanner, however is NOT a disk drive and thus won't should up as
    /dev/sda. It will show up as /dev/sg<mumble> (/dev/sgX == *generic*
    SCSI device.) You'll need the XSANE and SANE packages, which includes drivers
    and GIMP plugins for most SCSI scanners.

    Probably not.

    Is there some reason you cannot just get yourself a real live SCSI
    controller board? You won't need a partitularly fancy one for a
    scanner. Actually, most SCSI scanners come with a simple SCSI card.
