Sounds like you already did the job. Just fulfill the agreement and give them digitals on a thumb drive and move on. Part of learning the trade is making mistakes and knowing the value of your product. If they insist on prints come up with a price for that and an album as an add-on. You do hold the copy to all images taken so you can decide to let them print themselves or you can force them to use you for printing. In the future you can create a standard rate for weddings with travel/time defined and when either is exceeded then the price goes up. All of these things and more should be documented in a contract before any wedding.
