The printer context is an extension of XFN policies.
A printer namespace can be named in the service context. A printer context is named by using the namespace identifier, printer, in the service context relative to
An organizational unit
For example, if org/east.sales names an organizational unit, then org/eastsales/service/printer names the printer service of the organizational unit east.sales. Thus, an individual printer named lp1 would be identified as: org/east.sales/service/printer/lp1.
There can be no other type of context subordinate to a printer.
