This would seem to be the poor man's version of setting up the batch file.
At least there is nothing to buy to make this work.

You can set up a permanantly running batch file on the pc with the
following.  It will only process a file once the HP has FTP'd it and then
will wait until a file is again FTP'd.

This batch file can also be set up as a "service" on the pc so that it will
start automatically each time the pc is re-booted.
