Tracking and charging for printing with PyKota

Tracking and charging for printing with PyKota:
"PyKota is a robust Linux-based open source print quota and print accounting system that runs via LDAP, MySQL, or PostgreSQL on the back end and CUPS and Samba on the front end. At our school, we have found it to be a powerful application capable of managing printers, users, groups, and accounting information using any currency."
