Front and Back Printing on Documents

Two banks of print hammers 10 are provided as shown in Fig. 1, the banks being located one above the other.

The type belt 12 has as shown in Fig. 2 two sets of characters, one oriented for printing on the back of the document 14 and the other for printing on the front.

The ribbon 15 can be fed past both sides of the document 14 as shown in Fig. 3, so that the top row of type prints on the back side and the bottom row of type prints on the front of the document. A wide ribbon 16 only half inked, could be used as shown in Fig. 4.

This arrangement allows increased thruput and capability to print on both sides of the document 14. Only a single type belt 12 is necessary as well as a single ribbon. It is low cost and could be made compatible with current printers with only minor changes.
