I had this exact same idea last week but it'd be a tough one to crack. The devil's in the details of the operation. You'd have to solve at least the following problems: Print/sorting/packaging/mailing, privacy (most of the stuff you "need" to print is confidential), timeliness (usually when I print I need it NOW, like when closing a sale on a house) But if you can solve them, or at least start to, I think it'd be a great opportunity.
