Sealed Offline Print-Job Provenance.

Every offline print job recorded and signed without any network dependency. 15 claims.

A method for recording the provenance of a print job produced entirely offline, in which the job content, settings, and target device are captured and sealed under a post-quantum signature held in operator-controlled hardware. The signed record is produced without any network call, so an operator can later prove what was printed, when, and on which device. Filed 01 to 02 June 2026 as GB2612768.8.
