How to count printed pages using HP Laserjet Printer

In my office, few users use windows XP professional and few windows 7. Most of them use Windows Server 2003. We need huge pages to print daily. My bosses ask me to count page print per day and he also gives me assessment to count how much page actually print by a toner due to count printing cost.
We use HP Laser jet 1010 printer which attached with a computer. We use this computer as print server and the print server is running Windows Server 2003.
How can I do this?
