1. A method of operating an inkjet printer comprising:
moving media past at least one printhead to receive ink drops ejected from the at least one printhead;
generating solvent vapor within a space above a volume of liquid solvent within a reservoir; and
operating at least one positive pressure source to direct a first stream and a second stream of solvent vapor toward the media passing the at least one printhead, the first stream and the second stream being on opposite sides of the at least one printhead in a process direction.
