Diagnoses

A check of the connectionString for the PDF Converter service instance showed the service was set to connect to host server E and instance itself was living on server E.

Resolution

1) Change the connectionString to match the appropriate server.

2) Refresh the service instance which forces the change to the corresponding SmartObjects.

After those two steps the SaveasPDF control would fire expectedly.
