A driver IC () for a printhead includes a first set of data side input/output pads () and a second set of data side input/output pads (). The driver IC further includes circuitry () that can select that data is to be input at the first set of pads and output at the second set of pads.

Dual input bi-directional printhead driver integrated circuit

A printhead with a variable exposure width having a plurality of exposure elements defining a given exposure width. A plurality of driver ICs are coupled to the exposure elements, each driver IC including a plurality of registers. A data bus is coupled to the plurality of driver ICs. Circuitry is provided in a first driver IC of the plurality of driver ICs for having data received from the data bus bypass the plurality of registers in the first driver IC to disable unused exposure elements of the plurality of exposure elements, whereby the exposure width can be varied from the given width, and data loading bandwidth is minimized.
