Abstract
An improvement in an ink jet printing system which uses a catcher or gutter to intercept drops of ink deflected from the ink jet printing stream. The ink drop catcher serves to remove the drops of ink which have collected on the face of the catcher by means of capillary paths extending from the face of the catcher to a porous block. The porous block may be connected to a vacuum souce for removing the ink from the printing head.
