Well, perhaps they are using the status lines, eg. "paper out", and
shoving it through at high speed this way.  So probably you can hook
up maybe 3 switches and be able to read their input.  I suspect the
transfer programs are using two lines, one for clock and one for data,
which would be sufficient.
