Yes, as S.zberg answered, this printer has to be part of the eligible list. Don't forget, that when we ask for a new ecotank later on, they will ask you for a printout of the printer with the amount of sheets printed.

Yes, if the printer model is on the eligible list, there should be no problem buying the card separately and registering on the Epson website. You just need a printer purchased within 30 days and its serial number and the card with the registration number to do so.
