Abstract
A driver IC (60) for a printhead includes a first set of data side input/output pads (62) and a second set of data side input/output pads (63). The driver IC further includes circuitry (100) that can select that data is to be input at the first set of pads and output at the second set of pads.
Claims19
A driver integrated circuit (IC) for a printhead, said driver IC comprising:
- a first set of data input/output pads;
- a second set of data input/output pads;
- and
- circuitry adapted to select that data is to be input at said first set of pads and output at said second set of pads.
1 more element
A method of processing printing data by a driver integrated circuit (IC) for a printhead, said method comprising:
- receiving input bits;
- based on the input bits, determining whether data will be input at first data pads on a short side of the driver IC or at second data pads on a long side of the driver IC;
- and
- based on the input bits, determining whether the data will be transmitted from left to right on the driver IC, or from right to left on the driver IC.
1 more element
A driver integrated circuit (IC) board for a printhead comprising:
- host data bus connections;
- a first driver IC having first short side pads coupled to said host data bus connections and having second short side pads;
- and
- a second driver IC having third short side pads coupled to said second short side pads.
