What is the effect of halftoning in a black and white printer?

Question

Options

• AIt increases the dpi.
• BIt varies the amount of toner per dot
• CIt provides grayscales
• DIt reduces paper usage by 50%.

• C
  96% (24)
• D
  4% (1)

Explanation

Halftoning simulates grayscale by varying the size and spacing of dots rather than the actual shade of ink - the human eye blends these patterns into perceived shades of gray, making option C correct. Option A is wrong because halftoning does not change the printer's resolution (dpi); it works within the existing dot grid. Option B is incorrect for most halftoning implementations - each dot is either printed or not (binary), not varied in toner density (that describes a different technique called dithering or analog printing). Option D is fabricated; halftoning has no direct relationship to paper consumption.

Memory tip: Think of newspaper photos up close - you see only black dots of different sizes, but step back and you see gray faces. That's halftoning: half the dots, full illusion of gray.
