Print button with password

I use my photobooth for pop-up events where customers use the iPad as a live view and are the ones who operate the booth but I have the display print button turned off, now if some customers would pay to have extra copies, i have to go to settings and manually show the print button then print the correct pictures. Is it possible where the display button can be displayed but onced pressed, it will need password to access so that customers cannot print extras on their own?
