settings.
P

The dots that make up a scanned image.
R
Resolution
A measurement that shows the quality (fineness) of an image. Resolution is displayed by the number of pixels within an
inch. Since image data is a collection of small dots (pixels), if the same image contains different amount of pixels, the one
with more pixels can express greater details. Therefore, the higher the resolution, the finer the image becomes.
