An energy conservation method that reduces power consumption
when the scanner is idle for a period of time.

scanners where the individual element is a square pixel.
Refers to your preferred method of using the scanner. The scanning
software automatically saves certain preferences, such as the location
of toolbars and the destination of a scan, that it detects during normal
use of the scanner. Some preferences are restored each time the

A measurement of the number of dots per inch (dpi) the printer is
capable of printing. Typical laser printers have resolutions of 600 dpi,
typical ink printers have resolutions of 300 dpi for photographs and 600
dpi for text, while imagesetters have resolutions of 1200 or 2400 dpi.
The more dots per inch, the smoother the output and the greater the
number of grayscale levels and colors the device can describe.

A type of black and white, gray, or color image or picture made up of a
matrix of individual pixels or dots. This is also referred to as a bitmap.
The measure of how many dots per inch (dpi) are scanned, displayed,
or printed. The greater the dpi, the greater the amount of detail that is
visible, and the larger the file size. The final output device (monitor,
printer) for a scanned image determines the resolution of the image.
For example, if you scan a picture at 600 dpi (the optimum) and your
printer is capable of printing at only 300 dpi, the printed image will be
no more than 300 dpi.
