CUPS Banner Page Configuration

Have been looking around for a while all over for a solution, but can’t find any good CUPS related support sites so I thought I’d try here.
I have created a personal CUPS banner page, and everything seems to work as expected EXCEPT: The “Show” field “job-originating-host-name” ALWAYS prints “localhost” and not the actual name of the host – Or even the IP number. I’m lost at how to resolve this and would appreciate any suggestions.
