A print head includes an inlet port that receives a flow of a phase-change ink and an outlet port that delivers the flow to a jet. The print head includes a flow path along a flow direction from the inlet port to the outlet port. The flow path has top and bottom planar surfaces, and further includes two or more elongated grooves in at least one of the top and bottom planar surfaces. The two or more elongated grooves are at an angle to the flow direction and have a threshold capillary dimension such that bubbles in the phase-change ink are directed along the elongated grooves.
