A printing system includes a filter, a printhead including nozzles through which liquid is emitted, and a liquid supply system in liquid communication with the printhead through the filter. The filter, an electroformed metal structure, includes a plurality of first recesses, a plurality of second recesses, a plurality of first pores, and a plurality of second pores. Each of the plurality of first recesses includes a first recess diameter and a first recess center-to-center spacing relative to each other. Each of the plurality of second recesses includes a second recess diameter and a second recess center-to-center spacing relative to each other. Each of the plurality of first pores is in fluid communication with a corresponding one of the plurality of first recesses and each of the plurality of second pores is in fluid communication with a corresponding one of the plurality of second recesses. In the filter, the first recess diameter is not equal to the second recess diameter and the first recess center-to-center spacing is not equal to the second recess center-to-center spacing.
