Printer cartridge incorporating printhead integrated circuit

1. A desktop printer comprising:

a printhead cartridge defining an ink reservoir and including a printhead integrated circuit having a plurality of micro-electromechanical nozzle arrangements, the ink reservoir and the printhead integrated circuit substantially spanning a width of a medium transfer path along which print medium is transported past the printhead cartridge;

a cradle for removably receiving the printhead cartridge, the cradle supplying data and power to the printhead cartridge; and

a capping mechanism attached to the cradle and actuatable between an open position where the nozzle arrangements are exposed, and a closed position where the nozzle arrangements are sealed, the capping mechanism substantially spanning a width of the medium transfer path.

2. The printer of claim 1 , wherein the capping mechanism is further actuatable to a blotting position in which the capping mechanism blots the nozzle arrangements.

3. The printer of claim 1 , further comprising a media input assembly supporting therein medium for printing, the input assembly arranged in a generally upright orientation with respect to the printhead cartridge.

4. The printer of claim 3 , wherein the input assembly is inclined between 90° and 160°.

5. The printer of claim 3 , wherein the printhead integrated circuit is arranged at a higher angle of inclination than that of the input assembly.

6. The printer of claim 1 , wherein the printhead integrated circuit has at least 20,000 nozzle arrangements.

7. The printer of claim 1 , wherein the printhead integrated circuit has at least 50,000 nozzle arrangements.
