It appears that if there are printables ready to be printed when loading a save, the choices are rolled when loading into the game; in other words, printable choices aren't actually saved when you save your game. This makes it extremely easy to get prime choice printables without having to reject all and wait awhile again.
Steps to Reproduce
1. Have printables available to be printed. 2. Save game. 3. Exit to main menu 4. Load save 5. Check possible printables. They will be different than before. 6. Repeat steps 4 & 5 several times and they will be different each time.
