Abstract
An example method of collecting liquid carrier from a vapour in a printing system includes: heating a vapour carrying a liquid carrier and passing the heated vapour carrying liquid carrier through a volume of liquid carrier. Liquid carrier carried in the heated vapour condenses into the volume of liquid carrier as it passes through the volume of liquid carrier.

A method of collecting liquid carrier from a vapour in a printing system, the method comprising:
- heating a vapour comprising liquid carrier;
- passing the heated vapour comprising liquid carrier through an inlet duct positioned beneath a reservoir containing liquid carrier;
- passing the heated vapour comprising liquid carrier upwardly from the inlet duct through a volume of liquid carrier contained in the reservoir;
- and
- cooling the volume of liquid carrier to 0° C. or less,
- wherein liquid carrier comprised in the heated vapour condenses into the volume of liquid carrier contained in the reservoir as the condensed liquid carrier comprised in the heated vapour passes through the volume of liquid carrier.
An apparatus for use in a printing system, the apparatus comprising;
- a reservoir to store a volume of liquid carrier;
- a cooler to cool the volume of liquid carrier stored in the reservoir to 0° C. or less;
- and
- an inlet duct positioned beneath the reservoir to cause a vapour comprising liquid carrier to pass upwardly from the inlet duct through the volume of liquid carrier stored in the reservoir,
- wherein liquid carrier comprised in the vapour condenses to join the liquid carrier stored in the reservoir.
A non-transitory computer-readable storage medium storing instructions that, when executed by a processor of a printing system, cause the processor to:
- control a cooler to cool a volume of liquid carrier stored in a reservoir to less than 0° C.;
- and
- control a heater to heat a vapour comprising liquid carrier, wherein the heated vapour comprising liquid carrier is passed through an inlet duct positioned below the reservoir containing the volume of liquid carrier and the vapour is passed through the volume of liquid carrier stored in the reservoir to condense liquid carrier comprised in the vapour.
