All,
The main problem I have with the diagram is that it shows a Cloud Print
Manager registering with the Cloud Print Service instead of the Cloud
Print Provider. In my (protocol centric) view a upon the receipt of a
registration request from a Cloud Print Service, or its agent, the
Cloud Print Provider instantiates a cloud environment specific
implementation of a Cloud Print Service. The requirements for that
implementation are that it implements the PWG Print Service interface,
exposes the appropriate objects and attributes, and externally conforms
to the state models codified in the PWG model. At a later time the
Cloud Print Manager will bind to the Cloud Print Service to provide
updated status and capability information and to process Print Jobs
destined for the physical printer(s) associated with the Cloud Print
Manager.
I expect the normal cardinality would be one physical device per Cloud
Print Manager and One Cloud Print Manager per Cloud Print Service. The
PWG model accommodates both Fan-Out and Fan-In of Printers. This allows
a Cloud Print Manager to "front end" a number of physical printers.
Those printers can be collocated (i.e., printer farm) or distributed
(e.g., FedEx printer in Google Cloud Print). Alternatively a single
physical device could be associated with a Cloud Print Manager that
registers multiple Cloud Print Services. The purpose of such a
configuration could be to present different capabilities and/or
different defaults for each of the Cloud Print Services.
The [Print] Client is shown sending an Association request to the Cloud
Print Provider. Once the association is established and based on the
policies in place for the associated user, a set of Cloud Print Services
will be visible to the [Print] Client. The [Print] Client can then
interact (e.g., query status, query capabilities, submit print jobs)
with the Cloud Print Service.
