The maintenance operations can include preemptive actions that are taken upon a printer that is being operated in a certain environment, the preemptive actions based on evaluating operational statistics associated with a set of similar printers operated in a similar environment. The operational statistics, which are automatically accumulated over a period of time for various printers under various operating conditions, can be implemented in various ways, such as in the form of behavioral models and/or predictive models. In some embodiments, the behavioral models and/or predictive models indicate an expected-time-to-failure of a component when a printer is operated in a certain environment. The expected-time-to-failure information can be utilized to execute preemptive printer maintenance operations such as scheduling a replacement of the component ahead of the expected-time-to-failure. ## Claims ### Claim 1 A method comprising: deriving a first behavioral model based on an operating environment of a first set of printers;
