A toner fixing system for fixing toner onto a receiver medium includes a liquid-supply system for providing a heating liquid. A liquid-heating system warms the heating liquid to a temperature greater than a glass transition temperature of the toner. A rotatable liquid-blocking barrier has an inner surface and an outer surface. A media-transport system transports the receiver medium along a transport path in which the receiver medium is brought into contact with the outer surface of the liquid-blocking barrier in a contact zone. A liquid-delivery system impinges the warmed heating liquid onto the inner surface of the liquid-blocking barrier. Heat is transferred through the liquid-blocking barrier from the heating liquid to the toner, raising a temperature of the toner to a level above the toner glass transition temperature.
