Epson Stylus Photo 900 Ink Jet Printer

5760 x 720 optimized DPI is the highest addressable resolution that yields superior image quality and performance while keeping input files to a manageable size. EPSON printers typically need a file input size between 240 and 300 pixels per inch (ppi) to achieve maximum print quality. An 8" x 10" photo at 240 ppi is approximately 13 MB. This is a manageable file size for most users.
