Check this site out, its all about print adutis and what they do by a firm called Xeretec

Did you know that Print audits are very important to any business that carries out a lot of internal printing? Why is this the case, well as I found out, few businesses (mine included) knew the full amount they spend on print, copy and fax, all of which is a bit worrying, especially when such huge savings can be made. I found this site and have suggested to the MD that he contacts them, certainly looks like it could save us some money (and I may even get a raise).
