Try using fp_print_data_from_data() on a buffer that you just received 
from fp_print_data_get_data() -- does that work? If so, it indicates a 
problem with your storage mechanism.

The fingerprint data will contain NULL characters, and plenty of them. 
Perhaps you are having trouble storing them correctly.
