Abstract: In one example, a shroud to protect a group of printheads in a printhead assembly includes openings through which the printheads are exposed when the shroud is installed on the printhead assembly and an elongated protrusion along an exterior surface next to the openings to block print media from contacting the exposed part of the printheads during printing when the shroud is installed on the printhead assembly.

Abstract: An example air purging device includes a removable housing. The removable housing includes a first fluid interface to fluidically couple a fluid tube to the housing and a bore housing a plunger. In an example, movement of the plunger from a first orientation to a second orientation allows for the removal of the removable housing.

Abstract: In one example, a liquid delivery system for an inkjet type dispenser includes: a printhead unit; a reservoir separate from the printhead unit; a flow path from the reservoir through the printhead unit and back to the reservoir; an interconnect to connect Na removable liquid container to the flow path; and a single pump to pump ink along the flow path: from the reservoir through the printhead unit and back to the reservoir; and from the interconnect to the reservoir when a removable liquid container is connected to the interconnect.
