Abstract: A processor receives a print job, identifies possible extension marking materials to use to print the print job, and optimizes the order in which the extension marking materials will be used in multiple printing passes. A user interface outputs instructions to insert, into a receptacle, a first interchangeable supply container containing a first extension marking material that is in addition to base marking materials. A printing engine prints first markings (using the first extension marking material) that comprise a first portion of the print job. The user interface outputs instructions to return the partially printed print media to a sheet supply and to insert a second interchangeable supply container containing a second extension marking material. The printing engine prints second markings (using the second extension marking material) that comprise a second portion of the print job, on the partially printed print media, to produce the finally printed print media.
