Abstract: An interconnected printhead die and carrier substrate system for a printhead in hard-copy-producing devices used to print on print media includes a printhead die and a carrier substrate. The die and the substrate are coupled and each has an operative face separated from an inner face, and includes integrated circuits formed therein. At least three spacers are positioned between the die and substrate to define a space that is filled with an adhesive/under-fill layer. An electrical-connection region is located adjacent the inner faces of the die and substrate, and is effective to accommodate bilateral communication between integrated circuits formed on the die and the substrate. The die and the substrate may also have a stepped shape, and a cavity is formed by the stepped die and stepped substrate, with the electrical-connection region being located in the cavity. The electrical-connection region is also encapsulated with an encapsulant that may fill the cavity.

Abstract: A fluid ejecting device with a body defining an array of nozzles. The nozzles are arranged in an array along an array axis. The array has a first portion in which the nozzles are spaced apart along the array axis by a first pitch, and a second portion in which the nozzles are spaced apart by a different second pitch. The array may have a third portion between the first and second portions with a third pitch different from the first and second pitch. An assembly may include two or more of such fluid ejection devices, and the second portion of one print head may be aligned with the first portion of the other print head. Printers incorporating the fluid ejection devices and printing methods are also disclosed.

Abstract: A computer has an operating system with a graphical user interface. This computer also has a key manager for graphically associating objects, such as data or application programs, with keystrokes, such as Fn-Fx key combinations, where Fn is a special shift key and Fx is a numbered function key. A key group or folder contains icons which represent objects. This key group can be built or modified by the user by copying an icon contained in another program group or folder via a drag and drop or similar operation. The key manager interrogates the operating system for the contents of the key group, and receives a key array. The key array contains objects associated with keystrokes. The key manager then monitors the operating system for any keystrokes received from the user. Upon receipt of a keystroke, the key manager determines whether the keystroke is in the key group.
