This section covers PaperCut NG print monitoring architecture from a technical perspective. Knowledge of advanced networking is expected.
PaperCut NG is designed using the latest software design principles. An important design principle used is Service Oriented Architecture (SOA). PaperCut NG divides key operational areas into components. These components communicate using an XML Web Services standard. Two of the main services are:
| Service/Component | Description |
|---|---|
The Application Server | The central logic service responsible calculating user costs and providing the web and admin interface. |
Print Provider Service | A service responsible for monitoring and analyzing print jobs and reporting this information using XML Web Services to the application server. |
Table 12.1. PaperCut NG services/components
In a single server setup, an administrator does not need to be concerned with the two components as they automatically act as one (it's only noticeable in that two processes are running on the server). On a multi-server/system environment a deeper understanding of the architecture is required.
