A method of configuring a printing system includes providing a document key having an initial image and providing a printing system that includes a memory storing a first system setting. The method also includes scanning the document key and validating the initial image. The method can optionally include marking a first overlay image over at least a portion of the initial image, scanning the document key, and verifying the marking of the first overlay image thereon. The method also includes configuring or permitting the configuration of the printing system after the initial image has been validated or the marking of the first overlay, image on the initial image has been verified. A printing system that is capable of being configured using the document key is also included.
