Scanner settings: DPI (resolution)
Select the DPI (dots per inch) of the invoice in the DPI scroll box in the Scanner settings dialog.
The DPI option sets the resolution in dots per inch. You can normally choose among values between 100 and 400 DPI. Only the resolutions available for your scanner are available in the list box. Image processing is faster at lower resolutions.
For black and white scanning, we recommend the default setting (300 DPI) in most cases.
For grayscale and color scanning, we recommend 150 DPI.
