But I guess that even if the Printer cannot communicate with the output
device, the IPP client would still like the Printer to try synchronize and
would not suspect that there was any reason to specify "false"

[Note: This is beyond my range of expertise.] Apparently it's useful to
somebody in the case where the Printer cannot communicate with the output
device. In this case, the Printer cannot be shut down with synchronization.
However, the Printer can be shut down without synchronization, which allows
any previously hung operations to complete.

Hmmm. In our case, on Shutdown, "non-process-run-out"='true' is only valid
