Expands Windows applications print outputs into multiple pages. You can make up to 25 times large print documents and posters with regular A4 printers. Most of Windows applications can work with Print Expander. You can use your favorite application software and existing data files to make data and do not need to learn about new software to make or edit data. Since the expansion is done in vector data rather than raster image data, the printing speed is fast and you can get clear large characters printed with no shaggy.
