摘要： In one example in accordance with the present disclosure a flexible printhead is described. The printhead includes a number of printhead die, a printhead die including a number of nozzles to deposit an amount of fluid onto a print medium. The printhead also includes a fluid delivery system to deliver the amount of fluid from a fluid supply to the number of nozzles. The printhead also includes a number of electrical circuits to electronically couple the number of printhead die with a printing device. The printhead also includes a flexible substrate on which the number of printhead die and the number of electrical circuits are mounted.

摘要： A fluid manifold may include a number of blades and a number of end pieces securing the blades in place wherein the fluid manifold interfaces between a printhead die and a number of fluid source slots. A method of manufacturing a fluid manifold may include arranging a number of metal blades to form a relatively larger pitch between blades on a bottom side of the arranged blades than on a top side the arranged blades and mounting the arranged blades to a mounting structure formed to receive each blade as arranged.

摘要： A print bar may include a mounting structure and a printhead mounted to the mounting structure. The printed may include multiple printhead dies molded into a monolithic body and arranged parallel to one another in the body. The body may have multiple channels therein through which printing fluid may pass directly to the dies.

摘要： A microfluidic device includes a microfluidic chamber fluidly coupled to an inlet port and an outlet port, a semiconductor microchip including fluid active circuitry and transistor circuitry, and a bed of solid supports positioned within the microfluidic chamber fluidly positioned between the inlet port and the outlet port. The transistor circuitry in this example provides onboard logic at the semiconductor microchip to control fluid active circuitry. The semiconductor microchip also defines a portion of the microfluidic chamber.

摘要： In one example in accordance with the present disclosure a printer cartridge is described. The printer cartridge includes multiple backpressure chambers in fluid communication with a shared free fluid chamber. The backpressure chambers are to supply a fluid to nozzles of a portion of a fluidic ejection assembly and to provide backpressure to the nozzles of the fluidic ejection assembly during deposition of fluid onto a print medium.
