From July 1, 2022, only ONLINE cash registers must be integrated with the payment terminal.
ONLINE printers ARE NOT SUBJECT TO THIS REQUIREMENT!
This is due to the "Rozporządzenie Ministra Przedsiębiorczości i Technologii z dnia 28 maja 2018 r. w sprawie kryteriów i warunków technicznych, którym muszą odpowiadać kasy rejestrujące" ("Regulation of the Minister of Entrepreneurship and Technology of May 28, 2018 on the criteria and technical conditions that must be met by cash registers"). According to it, fiscal printers do not need to have a communication interface with a payment terminal.
