Method and system for print job processing

A method of processing a print job comprising the steps of:

• receiving print job data defining a print job from a requesting entity;
• assigning a reference to said print job;
• retrieving a reusable print job addendum bearing a representation of said reference from a reusable print job addendum reservoir, printing a print job hardcopy from said print job data and adding said reusable print job addendum to said print job hardcopy to produce a completed print job, and returning said reusable print job addendum to said reusable print job addendum reservoir,
• scanning said reusable print job addendum so as to extract said reference represented thereon, after said step of incorporating said reusable print job addendum with said print job,
• monitoring a delay between said steps of printing said print job incorporating a representation of said reference and of scanning a reusable print job addendum, and in a case where said delay exceeds a predetermined threshold carrying out a further notification step.
