Located in the central stairwell. A bank of 6 small printers, similar to the ones used to print out receipts in the library, are suspended from the top floor. Each printer represents an aisle in the LRS. As an object is requested, the printer corresponding to the aisle in which the object is currently housed, prints out the cover of the book and other relevant information. People walking up the stairs will be able to see what is being requested in real-time.
Over time the paper will pool on the floor.
The umbrella is to protect the printers from roof leakage.
