Double Letter size A standard paper size used in the United States and other countries (11 × 17 in.). dpi (dots per inch) A measurement of resolution which is used for scanners and printers. Higher dpi indicates better resolution. Driver A program specifically designed for operating systems, which enables interaction with a hardware device.

( simplex scanning mode) E Edge Extract A function which traces the boundaries between black and white areas, and extracts them as outlines.
