This is acceptable only if it's a copy which was authenticated as valid by a notary.
... if it is even possible for you to differ between a version that was printed at the company or a version that was sent as PDF from the company and printed out by me. They usually look completely the same in my case, though I for example chose to get 1-2 utility bills still via snail mail for exactly these AML/KYC reasons. Sometimes you get a weird web page with account overviews, but mostly I go the exact document that would have been printed + mailed, just as a PDF instead of a physical copy.
As hazek is watching, I don't dare to recommend to just print the damn thing on a good laser printer, fold it twice and scan it instead of complaining that PDFs aren't accepted... but I would recommend this, if he weren't here.
