I need an all-encompassing term that covers all kinds of written documents, except electronic ones: printed (on a printing press or the result of a computer printout) as well as hand-written documents.
I've used various alternatives in the past, documents in writing, documents on paper, documents in paper form(at), but none of them are really satisfactory. When it's obvious that hand-written documents can be omitted, I've usually used the term printed documents.
Edited to add: The context involves official documents and specifically the introduction of legally binding electronic documents. However, at times these need to be differentiated from hand-written documents from before the invention of the typewriter.
