1. A method comprising: receiving, into a computerized device, images of a previously printed document, a second document to be printed, and instructions to use previous layout parameters of said previously printed document to print said second document, without providing access to said previous layout parameters of said previously printed document; automatically reverse engineering said previous layout parameters used to print said previously printed document from said images of said previously printed document, without access to said previous layout parameters, using said computerized device, by detecting page boundaries, detecting page orientation, and detecting page sequencing within said images of said previously printed document; automatically, using said computerized device, preparing a print job ticket for said second document having job ticket layout parameters matching said previous layout parameters; and outputting, from said computerized device, said second document using said print job ticket to cause said second document to match said previous layout parameters of said previously printed document.

The method according to claim 1 , said detecting page boundaries being based on at least one of: finisher alignment marks in said image of said previously printed document; bounding boxes of non-white content in said image of said previously printed document; margin consistency in said images of said previously printed document; spacing of pages in said images of said previously printed document; logical page height and width in said images of said previously printed document; logical page size consistency in said images of said previously printed document; size of imposed sheet in said images of said previously printed document; and comparison of inferred page size within tolerances to commonly-used sizes in said images of said previously printed document.
