Hi guys,

In my experience, it is common to include elements of a model that "participate" in the model.

There will be an "element" of the model within a printer (or any other device) that interoperates with the cloud, and the reason that I think it makes sense to show it in the model is that this "element" has never existed before.

Showing just a "printer", indicates (at least to me), that there is no new functional element that needs to be added to the printer in order to realize the functionality of a cloud print service.

This may be true in some circumstances if the cloud print service used a legacy print protocol (IPP, etc.) to communicate with the printer, but I have a feeling that some cloud-specific element will be required in the printer -- at a minimum, it should probably be a "dotted-line" element in the printer.

R.

This addresses the canonical "printer proxy" configuration that is used for Google Cloud Print and other cloud printing solutions and preserves our ability to hand-wave the implementation details between the proxy/manager and physical printer.
