Abstract
In one example, a printhead assembly module includes an upstream row of printheads and a downstream row of printheads and a flow structure to distribute printing fluids to the printheads. The upstream and downstream rows of printheads are offset from one another such that a printhead in the upstream row extends past the downstream row at one end of the module and a printhead in the downstream row extends past the upstream row at the other end of the module. The flow structure includes a plate, slots in the plate to carry printing fluid to the printheads, and corresponding channels in the plate to distribute printing fluid to the slots. The slots and channels are arranged on the plate such that the arrangement is the same when rotated 180° about an axis of symmetry located at the geometric center of the arrangement.
