An application-to-application communication interface between an
accounting service application and a printer agent application resides on
a computer network. The interface is embodied as novel application
programming interface (API) functions or calls between the applications
that provide accounting support for print services, including tracking
the production of print jobs and the resources consumed by those jobs.
The accounting support services provided by the novel API communication
interface facilitate computing of charges by the accounting application
for print services and materials used by print clients.
