how can force software to read a security key in 2nd PC

hi, I have this software that reads a security key on paralel port. We are changing our PC to a new ones, and my new PC has no paralel port. So, how can I force the software to read the security key I if put it on a 2nd PC that has a paralel port… all this through my office LAN?

NEW PC WITH THE SOFTWARE —>
LAN —>
OLD PC – PARALEL PORT —>
SECURITY KEY

Thanks!
