1. A print cartridge assembly for a mobile handset, the assembly comprising:

  • a chassis defining a number of slots for operatively receiving ink bearing structures therein, the chassis defining a plurality of tortuous ink paths for supplying ink from the ink bearing structures to a printhead integrated circuit mounted to said chassis;

    a media drive shaft mounted to said chassis;

    a resilient surface for engaging the sheets of media substrate, the resilient surface configured to be inclined to the print media path when the print cartridge assembly is installed into the mobile handset such that a leading edge of each of the sheets of media substrate is guided to the drive shaft as the sheet of media substrate slides over the resilient surface such that during printing the sheets of media substrate slides are biased by spring fingers against the drive shaft; and

    power and data contacts defined on said chassis, the contacts in signal communication with the printhead integrated circuit to facilitate supply of power and data signals from a controller of the mobile handset to the integrated circuit.
