Please consider the following questions.
From which shed should I take it?
To which house should I send it?
From which printer is it being printed?
Are they correct?
Yes.
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?*
In the English question, you have to start either by a W H pronoun like who, how, ...etc or by an auxiliary verb. It is unnatural to start a question by a preposition.
