Abstract: An apparatus includes a plurality of nozzles configured to eject fluid and a fluid ejection array controller connected to the plurality of nozzles. The nozzles are arranged into a plurality of primitives, and the primitives are further arranged into a plurality of virtual primitives that each includes at least two primitives. The fluid ejection array controller generates ejection control data for each virtual primitive based on contents of a virtual primitive control packet. The ejection control data includes, for each virtual primitive, a first instruction instructing a first primitive of the virtual primitive to fire and a second instruction instructing a second primitive of the virtual primitive to not fire.

Abstract: A printhead includes an address line, data lines, a fire pulse line, and a plurality of primitives, each primitive corresponding to a different data line and including a plurality of activation devices, each activation device corresponding to a different address of a set of addresses. A buffer receives data packets, each data packet including address data representative of an address of the set of addresses and print data for each primitive corresponding to the address. For each data packet, the buffer directs the address data to address logic and places the print data on the respective data line, and the address logic encodes the address represented by the address data onto the address line. For each primitive, the activation device corresponding to the address on the address bus activates a corresponding primitive function based on the corresponding print data when a fire pulse is present on the fire pulse line.

Abstract: A printhead system to reduce peak energy usage may include a printhead including a plurality of primitives including nozzles. A printhead control module may control the printhead to increase printed pixel resolution and to reduce peak pixel fill density for print media. The printhead control module may further control the printhead such that all the nozzles with a same address generally disposed in a column do not fire at the same time.

Abstract: In some examples, a circuit for a fluid ejection device includes an energy delivery device and a circuit layer. The circuit layer includes first and second activation devices connected to the energy delivery device, the first and second activation devices to activate the energy delivery device, first drive logic coupled to the first activation device, and second drive logic coupled to the second activation device. An interconnect layer couples a same address selection signal to the first drive logic and the second drive logic.

Abstract: A printhead including an address line for communicating a set of addresses and a number of primitives, each primitive including a plurality of controllable activation devices coupled to the address line, each switch corresponding to at least one address of the set of addresses, each address corresponding to one of a number of primitive functions. A buffer receives a series of data packets, each data packet including address bits representative of one address of the set of addresses. Address logic receives the address bits from the buffer, wherein for each data packet the address logic encodes the address represented by the address bits onto the address line, and wherein the at least one switch corresponding to the address activates the primitive function corresponding to address.

Abstract: A print component includes an address line, data lines, a fire pulse line, and a plurality of primitives, each primitive corresponding to a different data line and including a plurality of activation devices each corresponding to a different address of a set of addresses. A buffer receives data packets each including address data representative of an address of the set of addresses and print data for each primitive, places the print data on the respective data line of the corresponding primitive, and directs the address data to address logic which encodes the address data onto the address line in the order of reception of the address data by the buffer via the data packets. For each primitive, the activation device corresponding to the address on the address line activates a corresponding primitive function based on the corresponding print data when a fire pulse is present on the fire pulse line.
