In present day impact printers, the trend is away from direct operator interaction on a real time basis, e.g., operator at the keyboard of a typewriter. Consequently, many present-day impact printers, operator visibility of the current print line has been eliminated; it is considered unnecessary since there is no direct operator interaction with the printer with respect to the current print line. However, there still remain circumstances when it would be desirable for the operator to be able to view the print line. These circumstances are usually associated with the stoppage of the printer for either maintenance, repair or some form of visual error checking. The present expedient is a simple and inexpensive means for providing operator visibility of the last print line whenever the impact printer comes to a stop.
