Request Tracker Concerns

Hi RT users

Im using RT 4.0.4 and currently now its under testing for implementation. I have some issues to clarify regarding RT and hope you guide or give some suggestions, answers for this.

Can i print/ review all ticket created for hardcopy purposes.
Ticket number needs to be format of YEARMONTHDAYxxxx
Example: #201707310001 would be the 1st ticket for today.
Is there a possibility for the requestor to have first approval of his/her supervisor before creating a ticket?
Thanks in advance

Hope you guide me for this
