Logical and virtual nozzle-fire-restart-line for fluid-ejection device

A method for performance by a fluid-ejection mechanism of a fluid-ejection device, comprising:

• listening for assertion of a logical and virtual nozzle-fire-restart line asserted by a controller communicatively connected to the fluid-ejection, to discern 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 of the fluid-ejection mechanism has been transmitted by the controller to the fluid-ejection mechanism over the physical data lines;
• upon the controller asserting the logical and virtual nozzle-fire-restart line, receiving the nozzle data sent by the controller in the predetermined sequence over the physical data lines;
• and,
• ejecting fluid from a plurality of fluid-ejection nozzles of the fluid-ejection mechanism in accordance with the nozzle data received from the controller.

A computer-readable medium having one or more computer programs that are executable by a fluid-ejection mechanism of a fluid-ejection device for the fluid-ejection mechanism to perform a method comprising:

• where a physical nozzle-fire-restart line communicatively connects the fluid-ejection mechanism to a controller of the fluid-ejection device,
• listening for the controller to assert the physical nozzle-fire-restart line before beginning to discern 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 of the fluid-ejection mechanism has been transmitted by the controller to the fluid-ejection mechanism over a plurality of physical data lines communicatively connecting the fluid-ejection mechanism to the controller;
• and,
• upon the controller asserting the physical nozzle-fire-restart line, receiving the nozzle data sent by the controller in the predetermined sequence over the physical data lines;
• where no physical nozzle-fire-restart line communicatively connects the fluid-ejection mechanism to the controller,
• listening for the controller to assert a logical and virtual nozzle-fire-restart line, to discern that the first data sub-packet of the new data packet of the nozzle data for the predetermined sequence of the fluid-ejection nozzles has been transmitted over the physical data lines;
• upon the controller asserting the logical and virtual nozzle-fire-restart line, receiving the nozzle data sent by the controller in the predetermined sequence over the physical data lines;
• and,
• ejecting fluid from a plurality of fluid-ejection nozzles of the fluid-ejection mechanism in accordance with the nozzle data received from the controller.
