I donated 2 laptops as well as a wireless printer to a shelter. is that a household item and how do I figure cost

Yes, it's a household item.  The cost is what you paid for it.  As far as the donated value, you can use what you would sell it for at a garage sale or thrift store.  You might consider checking online to see what your brands are selling for used as that may give you a good estimate of the donation value.
