Logical and virtual nozzle-fire-restart-line for fluid-ejection device |
| 摘要 |
A fluid-ejection device includes physical data lines, a controller, and a fluid-ejection mechanism. The physical data lines communicatively connect the controller and the fluid-ejection mechanism. The controller is to assert a logical and virtual nozzle-fire-restart line to denote that a first data sub-packet of a new data packet of nozzle data for a predetermined sequence of fluid-ejection nozzles of the fluid-ejection mechanism is being transmitted over the physical data lines. The fluid-ejection mechanism is to listen for the controller to assert the logical and virtual nozzle-fire-restart line, to discern that the first data sub-packet of the new data packet is being transmitted over the physical data lines. |

1. A fluid-ejection device comprising:
a plurality of physical data lines; a controller communicatively connected to the physical data lines and to assert a logical and virtual nozzle-fire-restart line to denote that a first data sub-packet of a new data packet of nozzle data for a predetermined sequence of a plurality of fluid-ejection nozzles has been transmitted over the physical data lines; and, a fluid-ejection mechanism including the plurality of fluid-ejection nozzles, the fluid-ejection mechanism communicatively connected to the physical data lines and to listen for the controller to assert the logical and virtual nozzle-fire-restart line to discern that the first data sub-packet of the new data packet has been transmitted over the physical data lines. |
