Abstract: A method informs a user of an ink jet printer of the end of life of a consumable. The consumable supplies ink to a printhead having a plurality of ink ejection nozzles and an associated plurality of ink jetting actuators, each of the plurality of ink jetting actuators being addressable. The printhead includes a plurality of address lines for facilitating selection of one or more of the plurality of ink jetting actuators. The method includes the steps of defining a notice threshold that is associated with a corresponding amount of ink remaining in the consumable; providing control logic for selectively controlling the plurality of address lines; determining whether the amount of ink remaining in the consumable has reached the notice threshold; and upon reaching the notice threshold, reducing an image density of images formed by the printhead by selectively disabling at least one of the plurality of address lines.

Abstract: An apparatus for connecting a printer to a cellular radio system. The adapter allows the printer to conduct facsimile operations. The adapter has a facsimile module which includes executable instructions for decoding fax data and processing the fax data to generate print data for printing; a cell radio; one or more communication ports having at least one of the communication ports in communication with the printer; and a data encoder in communication with the facsimile module and the cell radio. The data encoder is configured to convert data transmitted between the facsimile module and the cell radio.
