When do I need to allow the printing of checks in 1C-Bitrix?

Question

1C-Bitrix

Question from the examination course (One or more answer options)

To print checks, you must set the "Allow printing of checks" flag in the payment system settings if the cash register is connected:
through the "1C-Bitrix.Cashier" application
through integration with "1C"
through online services

Actually, I know that when paying through Sberbank acquiring, this condition is not necessary. However, I read in other sources that this is necessary. Tell me, what answers are more real here?
