I activated the eprint features on my printer quite long ago, and I forgot the e-mail I used to attach my printer to.
As I purchased a second printer, I created a new ID to activate the eprint services, and I tried to add my old printer to it, but I get a message saying that it is already connected to another ID, and that I should delete it from that ID.
How can I recover the old ID or just attach the printer to the new one ?
