Operating System: Windows 3.1 (Note: might work with other versions of this os.)
1. Solves the problem of editing sharpness parameter in standalone mode. In the former version, press ESC button in the layer of edit-sharpness will not retrieve original value but keep modified value instead.
2. Resolves a "Paper Jam" problem. (Paper may stop before printing or during printing because of unstable sensor detection of photo papers.)
3. Improves a "ribbon out" problem which happens when the ribbon is not really finished.
