Is a constant connection of the cash register with CRK (Central Repository of Cash Registers) required? What fields are required to be completed in the printout header? Until when will it be possible to exchange fiscal memories in devices with electronic copy? If the cash register communicates with CRK via Ethernet or WiFi, is it possible to use the same connection to communicate with the cash register from the computer (sales system)? There is a connection to CRK and the icon is crossed out - why?
