A focused spray jet printing system according to an exemplary embodiment of the present invention may include an atomization unit which atomizes ink by a carrier gas to make generate atomization droplets; a head unit including a virtual impactor which uniformizes sizes of supply atomization droplets ejected from the atomization unit to eject uniform atomization droplets; a focusing unit which is provided in the head unit to focus the uniform atomization droplets introduced into the head unit with sheath gas to spray the uniform atomization droplets onto a substrate; a sheath MFC which supplies the sheath gas, and a valve unit which is selectively connected to any one of an atomization droplet flow path which is formed in the head unit to flow the uniform atomization droplets to connect the virtual impactor and the focusing unit and a flow path formed at the outside of the head unit to flow the sheath gas.

In one example, an aerosol control system for a printer includes an air knife to discharge a sheet of air into a flow of aerosol along a moving print substrate web and a vacuum near the air knife to suck up aerosol from the flow simultaneously with the air knife discharging air into the flow.

A printing assembly has a frame having two side walls and has at least one cross member which extends at least in a transverse direction between the side walls and which has at least one supporting body which can be moved in relation to the frame in at least one parking direction and which extends at least in the transverse direction. At least one printing head is arranged on the supporting body and can be moved jointly with the supporting body. At least one first contact point, which is arranged on the supporting body, and at least one second contact point, which is arranged on the cross member, form a first contact-point pair. The first contact points lie opposite each other in the parking direction and are one of in contact and can be brought into contact with each other. At least one third contact point, which is arranged on the supporting body, and at least one fourth contact point, which is arranged on the cross member, form a second contact-point pair. The second contact points lie opposite each other at least at times at least also in a supporting direction orthogonal to the parking direction and orthogonal to the transverse direction and are one of in contact and can be brought into contact with each other.
