What’s the difference between "Registration Card" and "Registration Card Batch" in the options menu on the reservation search screen?

“Registration Card” gives you the printout of the register card of the current reservation you’ve selected. On the other hand, “Register Card Batch” gives you the printout of the register cards of all the results of your filtration. In the example below, if you click “Registration Card” you’ll get the register card of the guest named “Onur Demir” while if you click “Registration Card Batch”, you’ll get the printout of 5 CBS Travel reservations dated 15 May 2019.
