An ink jet printer includes a carrier for mounting a first printhead and a second printhead. A first ink reservoir is coupled in fluid communication with the first printhead, and contains a chromatic dye-based ink. A second ink reservoir is coupled in fluid communication with the second printhead, and contains a chromatic pigment-based ink.

Disclosed is an ink jet printhead apparatus for modulating drop size. Drop size modulation is achieved by providing an ink jet printhead chip for use in an ink jet printhead having a cavity in communication with a supply of ink and a nozzle. The chip includes an unitary actuator having a first active section and a second active section. The first and second active sections are defined at a substantially equal distance from the nozzle by a location of attachment of at least three conductors.

The invention is directed to an ink jet cartridge assembly, including a cartridge body and a print head. The cartridge body includes a die cavity and at least one groove disposed in communication with the die cavity and with an ambient environment. The print head is disposed at least partially within the die cavity. An adhesive is disposed within the die cavity between the body and the print head for bonding the print head to the body. The at least one groove defines a vent to the ambient atmosphere for a gas which may be produced during curing of the adhesive.
