 Dots per inch.  The number of printed dots per square inch of a print.  The more dots per inch, the smoother and generally higher quality the print will be.  The dimension in pixels of your image on any given length divided by the DPI will give you the size of your print for that dimension.  For example, if you had a 3000 x 2000 image, printing at 100 DPI would yield a 30" x 20" print. Printing that same image at 1000 DPI would yield a 3" x 2" print. Dots per inch.  The number of printed dots per square inch of a print.  The more dots per inch, the smoother and generally higher quality the print will be.  The dimension in pixels of your image on any given length divided by the DPI will give you the size of your print for that dimension.  For example, if you had a 3000 x 2000 image, printing at 100 DPI would yield a 30" x 20" print.
