a print cartridge having a core defining a plurality of ink storage reservoirs and a length of print media wound upon the core, the print cartridge also having a roller assembly for feeding the print media from the core; and

a printhead assembly having a chassis, a pair of printhead supports extending from the chassis and an ink ejection printhead supported by the supports to print ink from the reservoirs upon the fed print media;

wherein the printhead assembly further includes a flexible printed circuit board (PCB) electrically connected to the printhead, the flexible PCB carrying busbars to supply power to the printhead;

wherein the printhead assembly further includes a quality assurance (QA) integrated circuit mounted to the PCB and configured to authenticate the print cartridge.

2. A print cartridge assembly as claimed in claim 1 , wherein the chassis defines a well in which a worm gear of a print media separating means is located.

3. A print cartridge assembly as claimed in claim 1 , wherein the roller assembly includes a triplet of rollers with one of the rollers being driven.

4. A print cartridge assembly as claimed in claim 1 , wherein the printhead assembly includes a capping mechanism supported, in a displaceable manner, on the chassis to be displaceable towards and away from the printhead.
