I respectfully disagree : any backend already knows the jobid, print
queue name (and user name), so can retrieve the job-originating-host-name
and job-originating-user-name attributes for a job through a single
IPP_GET_JOB_ATTRIBUTES query to http://localhost:631

Once these values are known, your backend can interact with a client
side application which expects incoming connexions from the print
server (your backend).
