Abstract:
1. An inkjet cartridge, comprising: a collapsible ink reservoir adapted for generating a negative pressure therein and the ink reservoir has an opening through which ink is supplied to a printhead in fluid communication with the ink reservoir; the printhead having a plurality of nozzles in fluid communication with the ink reservoir and there being a fluid head pressure at the nozzles when the inkjet cartridge and printhead are disposed in a horizontal printing position which fluid head pressure is substantially the same as a fluid head pressure at the nozzles when the inkjet cartridge and printhead are disposed in a vertical printing position; and wherein the ink reservoir has an axis of symmetry disposed at an angle of 45 degrees relative to a surface of the printhead measured from a center point of the nozzles through the ink reservoir, and the ink reservoir can be rotated about this axis for printing in either the horizontal printing position or vertical printing position.
