| 1. A system for interconnecting a printhead cartridge and a cradle unit for supporting the printhead cartridge, the system
comprising:
an interface at which the printhead cartridge is removably engageable with the cradle unit, the interface comprising connections
for connecting the printhead cartridge with a power supply and print control circuitry of the cradle unit; and
a power storage circuit incorporated in the interface for storing at least some of the power being supplied to the printhead
cartridge from the power supply,
wherein the interface incorporates a first printed circuit board, the connections and power storage circuit being arranged
on the first printed circuit board, and the print control circuitry is incorporated on a second printed circuit board, and
the first and second printed circuit boards have complementary connectors which cooperate to provide the connection of the
printhead cartridge and print control circuitry, the complementary connectors being arranged so that the first printed circuit
board is able to pivot with respect to the second printed circuit board.
