Abstract

In point-of-sale terminals a situation exists where it is necessary to provide printing on the top surface of a user-inserted slip so that the operator can view the process of printing and follow instructions that may be printed on the slip. The normal point-of-sale terminal often utilizes a wire matrix print-head mechanism for printing journal receipts and other information, but these print heads are often oriented to print in the vertical plane or in a position which is not viewable directly. This complication introduces the necessity of performing a back printing operation for such slips when the print head is oriented in the vertical direction to print on the underside of journal roll or receipt tapes.
