Well, yes, that is also part of Mom's job as Person In Charge Of Donated Junk: to very politely tell people, "sorry, I don't think anybody would want that, you should probably just take it to the recycle center." (Also to be the familiar face who talks to the contacts at other places and makes sure they know they're allowed to say no to offers.)

Although frankly I don't know if I've ever known an inkjet printer that wasn't buggy and demi-functional right out of the box. :P (When we cleaned out the church's storage areas last fall we found four of them, all in at least some state of functional-ness. Two of them sold at the rummage sale - with warnings; one is being used, and the other got put back into storage for when that one hits complete nonfunctional-ness.)
