Printing the blocked PO in GTS

Hello Experts,

I have created the Purchase Order and that has been blocked in GTS. Still I am able to printout the PO and allowing me to send the fax for blocked PO. If the PO is blocked in GTS, we don't want to allow to print the PO or send a fax to vendor. What am I missing? Thanks in advance.

with best regards
