If you have contracted an agency to produce your document, they will print it or have it typeset, as per your instructions. This normally includes reviewing galleys for typesetting mistakes.

Many companies choose to produce the final translations on their own. This sometimes saves the expense of outsourcing the service. However, always have the agency or translator perform final proofing (this is no time to introduce unnecessary changes or have the copy checked by individuals who do not know the language in question!).
