The IPP model doesn't have the concept of an "IPP Server". There is only an IPP
Printer object, which logically consists of a network interface and one or more
output devices. Physically, an IPP Printer object could be a PC with an
attached printer, or a dedicated print server with attached printers, or a
printer with an embedded network print device. Refer to Section 2.1 of the IPP
Model and Semantics document for a more complete explanation.

In short, the interfaces between the various physical elements which make up
your logical Printer Object are up to you.

The required and optional functionality of the IPP Printer object are well
defined in the Model document. Again, there is no concept of a separate print
server and print device; they are viewed as a single IPP Printer object and any
interfaces internal to that object fall outside the scope of IPP.

No.
