Understanding Scanner Terminology
When you scan an image, several words pop out at you immediately since
you generally have to make selections from the software screen before
scanning. Some of the options that you’ll come across include color
mode, resolution, source, moiré, and output size. Some abbreviations
and/or proper names that you’ll see include WIA, TWAIN, OCR, DPI, and
TIFF. While some of these terms are probably familiar to you, others
