Here is a perfect example of the breakdown in terminology concerning scanning and printing. And its no surprise that it is confusing when the manufacturers add to the confusion. Epson printers don't really put down 720 dots per inch when you choose that option in the driver. You're not sending it a 720 dots per inch file anyway, 'cause there is no such thing. Henry
