It might be a good idea to find a better definition then.

With "photo-card" you're referring to memory cards as used by digital
cameras?

So, once you added that, would it be possible to use SANE to read a
memory card in a PhotoSmart printer? Hmm. Normally I'd still refer to
a device like this as a "printer," but I guess that would be very
confusing ;-)

Does it make sense at all to lump all of these devices together under
a *single* term when their capabilities vary so widely?
