    This should be fine; your dmesg output indicates that the values are
    indeed correct and that the BIOS isn't lying. But you could try just
    taking the options line out altogether. The only thing it's doing
    there is turning interrupt-driven printing on, which isn't really that
    much of a big gain.

    You might also want to turn off the IEEE 1284 probe, which might be
    upsetting the printer. Add this line to do that:

    alias parport_probe off

    > mknod -m 660 /dev/lp0 c 6 0

    This is fine.

    Do you have a different parallel port cable you can test with? Are
    there any messages in the dmesg output after you try that command?
