TWAIN
Standard interface over which software applications can control the operation of
scanners and other such imaging devices. All software applications bundled with
your scanner comply with the TWAIN standard, and can therefore access your
scanner through the EPSON TWAIN interface.
Zoom
Refers to enlargement or reduction of an image when reproducing it on the monitor
or target device. The scanner zooms in on an image (enlarges it) by reading a
greater number of pixels per unit area, or zooms out by reading a smaller number
of pixels. The target device, because it has a fixed resolution (fixed number of dots
per inch), responds to the greater or lesser number of dots by increasing or
decreasing the size of the image.
