In a pen plotter, a plotting system for generating and delivering vaporized ink to an aerosol pen which is designed to deliver a precision, controlled stream of ink to the media surface without having to come into contact with it. This is achieved by vaporizing ink in a chamber and delivering it to an ink vapor aerosol pen through tubing which is designed to absorb and recover any ink vapor droplets that may have condensed therein and thus obstruct the vapor path. The aerosol pen is designed to dispense the ink vapor as a stream which converges to a fine point thereby allowing a precise image to be plotted on the media surface. As with the vapor delivery tubing, the aerosol pen is also designed to absorb and recover condensed ink vapor droplets. An interrupter moved into and out of the ink vapor stream to act as a valve for the stream so as to stop and start marking on the media by the stream. Intercepted ink is recycled back to the holding chamber.
