Abstract: There is provided a device for printing an impression of both postal codes and postage stamps on envelopes which comprises a frame having a slot to receive an envelope so that the envelope is in position to be appropriately printed with an impression of a postal code and postage stamp. Sensors are provided within the slot to indicate when the envelope is appropriately positioned for printing an impression of the postal code and postage stamp. A printer is provided within the frame to print an impression of a predefined postal code in machine readable form and a variable postage amount subtracted from an electronic fund of stored postage on an envelope appropriately positioned within the slot. A keyboard on the frame enables the selecting of both a postal code and a postage amount.
