It seems he wants to use a dongle which you put in the printer port of the
PC.
The dongle contains the identifying key.
I can imagine that using CreateFile, ReadFile the information in the dongle
might get accessible?
Am also curious on how to do that?

At work we also use software protected with dongles. Only after putting the
dongle in the printer port the printing process is not going well anymore.
