Billing codes
Billing codes assign print, scan, fax, or copy jobs to a specific code, and are typically used to track output on a project-basis. You can assign a billing code to an entire department, or to individual users.
When the user releases a print job, they can assign the job characteristics to a particular billing code. The print tracking information is logged to the selected billing code, rather than to the user or department who released or printed the job.
If you assign a billing code to a department, all users belonging to the department inherit the department billing codes.
