ABSTRACT:
An electronic input/output apparatus for a computer system which includes a computer and a computer screen, includes a mechanical mouse and a printhead integral with the mouse, both being attached to the computer through an electrical interconnection means. The mouse is represented by a cursor on the computer screen based on movement of the mouse. The electrical interconnection means provides data signals between the computer and the electronic input/output apparatus for the mouse and additionally for the printhead which is capable of printing data displayed on the computer screen which has been passed over by the cursor. The printhead, upon activation by a print button or the like, prints onto a substrate as the I/O apparatus is moved across the substrate. Control of the printing operation is done by monitoring and controlling the data sent to the printhead based on positional and velocity values obtainable by a tracking mechanism within the mouse.
