Can anyone give me an idea what print costs per page the following printers would be. Trying to put a more realistic message across over the useage of the printers at school. Just telling them how many prints they have done is not having an impact. Hope telling them in money terns would have more of an impact. Printers we use are HP2500n (colour laser), HP1015 (mono laser) and a Xerox 6180DN (colour laser).
