Just what size is are A4 and A3 prints? Also, I should note that I've often
heard/read people remark that they can print off scanned images up to such
and such size (e.g., 11"x14"), but I'm not always clear about just what size
the image is that is placed on the paper. What, for example, is the usual
image size for a print on A4 paper? Does it vary much?
