Abstract
A pen printer for converting data into printed form on a print sheet placed on a platen. The pen printer comprises a plurality of ink pens and a pen carriage mounted for reciprocating movement above the platen. The pen carriage has a device for removably attaching each of the ink pens juxtaposed in the direction of movement of the carriage. Pen actuators are mounted on the pen carriage apart from the ink pens with each pen actuator being responsive to an electrical signal for bringing a corresponding one of the ink pens toward the platen into contact with the print sheet. The pen printer also comprises a carriage actuator responsive to an electrical signal for moving the pen carriage and a sheet feed mechanism responsive to arrival of the pen carriage to at least one of first and second predetermined positions separated from each other for feeding the print sheet a predetermined length on the platen. A control circuit is provided for converting the data into electrical signals to control the pen actuators and the carriage actuator.
