As the drum spins, the ink is pushed through the tiny holes in the master onto the paper.   
Digital Zoom
Uses digital technology to enlarge an image. Digital zoom does not have moving parts. It is the electronic enlarging of the middle of an image. The pixels at the center portion of the CCD are digitally doubled to make the image appear larger on the display. Existing data is interpolated to create new data. Resolution is reduced as the center pixels are enlarged to fill the display. 
Dither
Creating the illusion of new colors and shades by varying the pattern of dots. Newspaper photographs, for example, are dithered. If you look closely, you can see that different shades of gray are produced by varying the patterns of black and white dots. There are no gray dots at all. 
Driver
Software that tells the computer how to interact with a device, such as a printer, hard disk, CD-ROM drive or scanner. For instance, you can't print unless you have a printer driver installed. 
Drum
The heart of a copier on which the image is formed. It consists of an aluminum core with multiple layers of light and charge sensitive material such as selenium, or an organic based material. 
Duplex copying/printing
