Abstract
A printer using a disposable ribbon which is fed from a feed section toward a take-up section of a feeding device upon completion of printing of each line of characters. The printer comprises a memory for storing position data representing a feed-side end of an active portion of the ribbon which has been used for the last printed line, the feed-side end being located on the side of the feed section of the feeding device, and another memory for storing another position data representing a take-up-side end of another active portion of the ribbon which is to be used for the next line of characters, the take-up-side end being located on the side of the take-up section of the feeding device. The printer further comprises a control device for controlling the operation of the feeding device so as to feed the ribbon until the feed-side end of the active ribbon portion for the last line reaches the take-up-side of the active ribbon portion for the next line if the above feed-side end is located nearer to the feed section than the above take-up section.
