What on earth would be the point?
To endure that printing the stamp is done from within the Java sandbox
so that only one print attempt per bar-code can be made.

An over-complex and ultimately useless solution! One can always hold the
print job at the spooler, and ask it to print multiple times...so that
would not be secure at all.

That's why it has to be done with unique barcodes.

Except that they're not unique if they can be printed multiple times.

The data's unique within RM's system; there's nothing stopping the user
from making multiple copies, but the data still only permits a single
*valid* entity.
