<pclass="howto">There are a lot of locations in almost every city that collect paper that cannot be used anymore. Luckly, nowadays, most of these locations, such as printing spaces, stationery shops, book makers, separate and recycle the materials they cannot use. Most of the times, these leftovers are in a very long rectangolar shape, do you know why? When you print, but the shape of your print doesn't 100% fit the paper sheet you are printing on, this produces a lot of leftovers, mainly on one side or two of the sheet. </p>
