A pay-for-usage system for hard copy devices such as printers charges for actual pages printed. A pay-for-capacity system charges for a specified capacity potentially reduced by unused capacity. A pay-for-capacity or pay-for-usage system includes hard copy devices coupled to an appliance server via an internal network. Printer usage information is accumulated in these hard copy devices, periodically uploaded to the appliance server, and later forwarded to a data repository or database server across a nonsecure network such as the Internet. The customer is then billed based on this usage information.
