Vent through a printhead support structure

摘要

In one example, a structure for supporting a printhead includes: a substrate having a first side and a second side; an inlet tower through which liquid may be introduced into the structure; an opening through the substrate near the inlet tower; and an air channel along the substrate connecting the opening in the substrate to the atmosphere.
