Abstract
A printhead includes a nozzle plate, a filter, and a plurality of walls. Portions of the nozzle plate define a plurality of nozzles. The filter, for example, a filter membrane, includes a plurality of pores grouped in a plurality of pore clusters. Each of the plurality of walls extends from the nozzle plate to the filter membrane to define a plurality of liquid chambers positioned between the nozzle plate and the filter membrane. Each liquid chamber of the plurality of liquid chambers is in fluid communication with a respective one of the plurality of nozzles. Each liquid chamber of the plurality of liquid chambers is in fluid communication with the plurality of pores of a respective one of the plurality of pore clusters. The respective one of the plurality of pore clusters includes two pore sub-clusters spaced apart from each other by a non-porous portion of the filter membrane.
