I have one computer set up in a common area with one login for everybody to use it. I am looking to buy a printer to connect to the computer with some type of system where when people print they are required to enter a userid and/or passcode either a) at the printer itself or b) on the computer from which they are printing in order for the printer to print. I also need the program/printer to log the number of pages they print so I can bill them appropriately. I know company printers have the capability to do something like this, but the difference between what I found online and what I am trying to do is that the user log in ID on the computer is universal and everyone uses it, so simply getting a program that shows which user printed the page will not work. If there is any programs or printers with this type of capability I would like to know. Thanks.
