The output quality of a printer is measured by

  • A.Dot per sq. inch
  • B.Dot per inch
  • C.Dots printed per unit time
  • D.All of the above

Answer: A

Correct answer: Dot per sq. inch

Print quality is a matter of resolution - how finely the dots are packed. It is quoted as dots per inch, usually for both directions (600 × 600 dpi), which amounts to a density over the printed area. The more dots in a given area, the smoother the curves and the finer the detail. Speed, quoted in pages per minute, is a separate matter and says nothing about quality.
