Abstract
A graphic recorder includes a moveable pen carriage and drive means associated with the pen carriage for causing it to travel back and forth under computer control. A media roller defines a continuous cylindrical member supported beneath the carriage path and coupled to a computer controlled media drive system. Recording pens supported on the pen carriage are selectively lowered into recording positions in which they write upon a flexible media and against the media roller directly.
