    I dunno. Do you mean that:

       echo 255 > /dev/lp0

    would set all eight data pins high (=send 255 to the parallel port)? If so,
    then that would indeed be enough. Is it really that simple? Is that why I
    couldn't find any simple c prog, because such a program isn't needed?

    Oki, I'll try it right away (well, maybe not right away cause I'm goiong to
    bed...).
