I have a Photosmart 5520 and very occasionally I have used the eprint option without problems. I have security set to "Allowed" email addresses only and there are only 2 listed addresses - mine and my daughter's.
Yesterday I received a series of prints that I hadn't sent and my daughter hadn't sent. The HP.com website advises going to Print History to ascertain where the prints came from and, if necessary, block the sending address. Unfortunately, nothing is listed.
I would be grateful for any advice.
Many thanks
