Abstract

An ink jet printing apparatus for printing addresses on documents being transported along an independently operated conveyor. The printing apparatus includes a control console, a printing arm telescopically received within the console, and an ink jet printing head mounted on a carriage which is vertically movable within the printing arm. A tachometer wheel is mounted on the printing carriage for contacting a document being transported past the printing head and generating a tachometer signal in response thereto. A programmed microprocessor generates printing control signals in synchronism with the tachometer signal.
