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.
