Hi All, I've got an old HP printer/scanner combo... Consumables are expensive, but otherwise it serves its purpose, well almost... The problem is the document scanner on it only does single sided scanning. My question is this: Is there an app that allows you to combine multi-page scans into one document? For example can I scan one side of a stack of double sided documents, then scan the reverse side, is there an app combine them into one document (and keep their scan order)? Hope someone else has this idiosyncratic first world problem (I don't want to buy another scanner/printer).
