Heh :-)  ... he said he knew how to do it in the web GUI. He wanted to do it via the C API.

I'm not sure if the C API provides hooks for that -- but in any case, the "c000NNN" control files in "/var/spool/cups/" do hold this info.

He could use brute force and run "strings -A 1 job-originating-host-name" against such a c-file, or he could build and run the "ipptest" utility ("test" subdirectory), and run it like this:

   cd test ;
   ./ipptest -v ipp://localhost:631/jobs/1737 get-job-attributes.test |grep job-originating-host-name

to get info about job ID 1737.
