Secure mobile printing method and system

A secure mobile printing method, comprising the steps of:

• initiating on a mobile device a first print job and a second print job;
• assigning on the mobile device a first job identifier for the first print job and a second job identifier for the second print job;
• selecting on the mobile device from a plurality of printers a printer for the first print job and the second print job;
• sending from the mobile device to the selected printer the first print job and the first job identifier whereby the first print job is locked on the selected printer;
• sending from the mobile device to the selected printer the second print job and the second job identifier whereby the second print job is locked on the selected printer;
• imaging by the mobile device a printed PIC for the selected printer on an exposed surface of the selected printer;
• resolving on the mobile device the printed PIC image to the first job identifier and the second job identifier;
• and
• sending from the mobile device to the selected printer the first job identifier whereby the first print job is unlocked on the selected printer and the second job identifier whereby the second print job is unlocked on the selected printer.

A mobile device, comprising:

• a processor;
• a user interface communicatively coupled with the processor;
• a network interface communicatively coupled with the processor;
• and
• a camera communicatively coupled with the processor, wherein in response to input on the user interface the mobile device under control of the processor initiates a print job, assigns a job identifier for the print job, selects from a plurality of printers a printer for the print job and sends to the selected printer via the network interface the print job and the job identifier whereby the print job is locked on the selected printer, and wherein in response to further input on the user interface the camera under control of the processor images a printed PIC for the selected printer on an exposed surface of the selected printer whereupon the mobile device under control of the processor resolves the printed PIC image to the job identifier and sends to the selected printer via the network interface the job identifier whereby the print job is unlocked on the selected printer.
