lpoptions applied when?

I was wondering at what points the options for a printer are applied?

Say that you have the following layout:


Host A        Relay B        Server C
+----+        +-----+        +------+
|    | =====> |     | =====> |      | = [Printer]
+----+        +-----+        +------+

Is this the way it goes:

* An application prints a document to cups on Host A.

* The pstops filter will be applied so that settings from ~/.lpoptions
and /etc/cups/lpoptions get applied.

* The document is sent via IPP to cups on Relay B.

* pstops is run on Relay B to get settings from /etc/cups/lpoptions.

* The document is sent via IPP to cups on Server C.

* pstops is run on Server C to get settings from /etc/cups/lpoptions.

* The document is sent to the printer.

In this scenario Host A has found the printer via broadcasts from Relay
B, but in Relay B the printer is added locally to make sure the jobs
actually pass through it.
