Abstract
An ink jet system printer has a printer head for emitting ink droplets toward a recording paper. Objectional ink mist is inevitably formed and diffused in various directions after the ink droplets impinge upon the recording paper. The printer head includes a first chamber for introducing the ink mist diffused in front of the printer head, a second chamber for accommodating an ink droplet issuance unit for emitting the ink droplets, and a fan system for creating an air flow directed from the first chamber to the second chamber, thereby effectively introducing the ink mist into the first chamber. A filter member is disposed in the first chamber for removing the ink mist introduced into the first chamber. The ink droplet issuance unit is disposed in the second chamber so that a stream of the ink droplets is inclined from a line perpendicular to the surface of the recording paper.
