    This is a bug: you ought to be able to print regardless of the port's
    mode. What exactly happens when you try to print, through the ZIP
    drive, when in EPP mode? Are there any kernel messages? What is the
    behaviour of this:

    # echo blah > /dev/lp0

    Being able to use more than one device at a time is kinda the
    _point_. :-)

    Do you still find it faster under 2.2? Can you show me timings? As I
    said, I found it quite a lot faster to do a 'cp', but I think a lot of
    that is to do with VM changes rather than anything in the driver.

    It probably won't help, although relevant sections of dmesg output
