Abstract

A thermal ink jet printer has an ink delivery system which enables rapid changes and increased operational speeds when changing between full color, highlight color and monochrome mode of operation. In response to selection of a desired mode, ink supply systems associated with particular cartridges are selectively purged and interconnected to ink supply systems of the colored inks which will be used in the selected operational modes.
