Hey Barbara,
If you are referring to add the Print Certificate link created in your event (so invitee can print their certificate from that page), it would not work.
If the certificate is displaying invitee specific information, the system needs to know which invitee has reached the page and should create a unique link so, an invitee can print his own certificate.
Since Archive page is a General page and does not need any login/authentication from the invitee, the Print Certificate data tag would not work.
Please let me know if I am misunderstanding and you are referring to a different type of certificate and I can certainly provide a workaround!Regards
