This is the amount of ink dots the printer will put on each pixel of your image.

PPI

Digital raster images are measured in pixels, or picture elements.

DPI

The DPI is set by the actual printer device and it is not something in the image for the graphic designer to manipulate.

PPI

How many pixels per inch is determined by the device you create the digital image with: camera, scanner, or graphics software and can be modified with a photo/paint editing software.
