US Patent 8055537 Customer satisfaction method and system for network printers

A method teaches monitoring at least one printing device via a communication network. A usage profile may be received from the printing device. The usage profile may include data that reflects usage of a consumable or a number of clicks by the printing device over a period of time. The usage profile may be compared to a service history profile to create a service-dependent usage profile. If the received service-dependent usage profile satisfies a reward criterion a user of the printing device may be provided with a reward.
