Abstract: For various embodiments of a printhead assembly or ink stick assembly of the present teachings, each an ink stick assembly can be a self-contained assembly, of which a plurality of self-contained ink stick assemblies can be readily interchanged into a printing system during a printing process. Various embodiments of a self-contained ink stick assembly can have a fluidic system that can include a local ink reservoir, which can be in fluid communication with a bulk ink reservoir. Filling of a bulk ink reservoir can be done in a manual or automated mode. According to the present teachings, a bulk ink reservoir can have a volume sufficient to provide a continuous supply of ink to a local ink reservoir over the course of a printing process.

Abstract: The present teachings disclose various embodiments of a printing system for printing a substrate, in which the printing system can be housed in a gas enclosure, where the environment within the enclosure can be maintained as a controlled printing environment. A controlled environment of the present teachings can include control of the type of gas environment within the gas enclosure, the size and level particulate matter within the enclosure, control of the temperature within the enclosure and control of lighting. Various embodiments of a printing system of the present teachings can include a bulk ink delivery system that can be external to a gas enclosure. A bulk ink delivery system according to the present teachings can supply ink to a local ink delivery system that is internal to the gas enclosure. Various embodiments of a local ink delivery system of the present teachings can be proximal to a printhead device assembly, and can include a two-stage ink supply having a local ink replenishment reservoir that is configured to supply a local ink dispensing reservoir to a constant volume. According to the present teachings, a local ink dispensing reservoir can be in flow communication with a plurality of printhead devices. As such, a two-stage local ink delivery system maintaining a constant volume in a local ink dispensing reservoir can provide constant head pressure to the plurality of printhead devices.
