This application works as another printer, in other words, to use it you only have to give the order to print a document and choose FinePrint as printer. An interface will open with the different options that it offers. With FinePrint you'll be able to print several pages on one, adjust the margins, add watermarks to the document, add a heading, adapt the page numbering or change the document to a scale of greys.
FinePrint also allows you to manage the images that you're going to print, selecting their resolution to be able to save as much ink as possible.
If you want to manage your printouts in a comfortable and simple way, try out FinePrint.
