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. |

1. A printing device comprising:
a processor; a user interface operatively connected to said processor; a printing engine operatively connected to said processor; a sheet supply supplying print media to said printing engine; permanent supply containers operatively connected to said processor, said permanent supply containers maintaining base marking materials used by said printing engine to print on said print media; and a receptacle operatively connected to said processor, said receptacle having a shape to connect to interchangeable supply containers maintaining extension marking materials used by said printing engine to print, said extension marking materials being different colors from said base marking materials, said processor receiving a print job using at least two of said extension marking materials, said user interface outputting instructions to insert, into said receptacle, a first interchangeable supply container maintaining a first extension marking material of said extension marking materials, said processor performing raster image processing to generate first markings and second markings, said printing engine printing said first markings comprising a first portion of said print job on said print media to produce partially printed print media, said first markings including markings made using said first extension marking material, said user interface outputting instructions to return said partially printed print media to said sheet supply and to insert, into said receptacle, a second interchangeable supply container maintaining a second extension marking material of said extension marking materials, said sheet supply supplying said partially printed print media to said printing engine, said printing engine printing said second markings comprising a second portion of said print job on said partially printed print media to produce finally printed print media, said second markings including markings made using said second extension marking material, and said first extension marking material being a different color from said second extension marking material. |
