Well i have scanned a bunch of paper work and it seems god the scanner will scan just about any paper 8 1/2" wide and a reciept up to 20 inches long for those long grocery reciepts.As for use i have scaned about 20 grocery recipts and you start to ntice how things you buy are going up in price its sort of depressing.
Anyways the only draw back is it does not have all the features of the windows version yet.They say it will be updated as this an advance release of the product and you will get updates for free for now
