Pixels per inch (ppi) - A measurement of image resolution that defines the size an image will print. The higher the ppi value, the better quality print you will get--but only up to a point. 300ppi is generally considered the point of diminishing returns when it comes to ink jet printing of digital photos. Dots per inch (dpi) - A measurement of printer resolution that defines how many dots of ink are placed on the page when the image is printed. Today's photo-quality ink jet printers have dpi resolution in the thousands (1200 to 4800 dpi) and will give you acceptable quality photo prints of images with 140-200 ppi resolution, and high quality prints of images with 200-300 ppi resolution.
