Selecting "print gift receipt" generates a bar code for the entire transaction. Individual items are not listed. The print receipt is interchangeable for anything in that transaction.
FYI as for Target gift cards, there is a separate "Inquiry" app for checking a gift card balance and if desired printing out the balance for the guest.
For non-Target gift cards and prepaid Amex/Mastercard/VISA cards, there is nothing available to print the balance. Those are nonrefundable. Guests with questions need to call the contact number on the back of the card.
