Abstract: Printheads and printers are described herein. In one example, a printhead includes a number of drop generators disposed in a first array and a second array. The drop generators in both the first array and the second array are spaced one dot pitch apart perpendicular to the motion of a print medium, and alternate between a high drop weight (HDW) drop generator and a low drop weight (LDW) drop generator. Each drop generator in the first array is in a line of the motion of the print medium with a corresponding drop generator in the second array, wherein each HDW drop generator in the first array is in line with an LDW drop generator in the second array, and each LDW drop generator in the first array is in line with an HDW drop generator in the second array.

Abstract: Printheads and printers are described herein. In one example, a printhead includes a plurality of nozzles configured to eject ink drops of different sizes wherein a low drop weight (LDW) drop is ejected through a nozzle with a circular bore (CB), and a high drop weight (HDW) drop is ejected through a nozzle with a non-circular bore (NCB).

Abstract: 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.
