Skenton, you’re correct he did say ‘scanning’. I think the subject changed somewhere and became printing.
Anyway, I never thought about document size when I do scan backs. I just put the documents in my printer to scan and they include letter and legal size. I think the company at the other end can print them any way they want because they would be in their computer. It isn’t a fax so the page size wouldn’t matter on my end. I have never had an issue with my scans.
