They're correct, but they also sound a little stilted. There used to be a myth that it's bad to end a sentence with a preposition, and in some languages it really doesn't make sense to end a sentence with a preposition, but it's often pretty natural in English, especially when the sentence is a question.
These sound more natural, at least in contemporary English:
Which shed should I take it from?
Which house should I send it to?
Which printer is it being printed from?*
