This apparatus employs a drum printer as both an interactive display de vice and for preparing a journal or transaction record in, for example, a self-service banking terminal. The printer is arranged for back printing so that the printed message is viewable through a window on the platen side of the paper.

Flexible print drum 1 is translatable along axis 2 and includes a plurality of print elements 3 on the outside surface. A print hammer, not shown, is oriented within the drum 1, and printing is accomplished by striking the inside wall of drum 1 to drive the selected print element 3 outward, forcing paper 4 against glass or plastic platen 5. A drum printer of this type is described more fully in U. S. Patent 3,913,722 by R. R. Bowdle and R. J. Laybourn for a Drum Printer.

Paper 4 is fed past viewing window 7 in frame 6, from supply 8 to take-up 9.

Type elements 3 are reversed, rendering the printed characters readable through window 7. Ribbon 10 is interposed between paper 4 and platen 5, so that during printing ink is transferred to paper 4 on the side to be viewed. After a line is printed, paper 4 is incremented one line up to bring the printed message into the view of the terminal operator. Alternatively, ribbon 10 may be eliminated and impact paper used, in which event the viewing window can be lowered to serve as the print platen to allow the operator to view the message as it develops.
