Cute. I wanted to make something like that for my mom (so friends and family could message her on it, not for strangers) but I never got around to it. She knew how to use email but didn’t check it very often, so a printer would have been more immediate. It would have to have been an impact printer though, since another family member (probably correctly) wanted to stay away from thermal paper on health grounds.

Maybe this is what you saw:
