Which unit is used to measure the resolution of a printer?
Answer: B
Correct answer: Dots per inch
Printer resolution is measured in dots per inch, the number of individual dots of ink or toner the printer can place along an inch. Higher figures give finer detail and smoother curves. Typical values are worth knowing: 300 dpi is adequate for ordinary text, 600 dpi is common on laser printers, and photographic work uses 1200 dpi or more. The distractors measure related but different things, and the set is a standard examination pairing. Pixels measure the resolution of a display or a digital image. Hertz measures a monitor’s refresh rate or a processor’s clock. Bits per second measures data transfer. The same unit dpi is used for scanners, where it means how finely the original is sampled - and it is worth noting that an image scanned at 300 dpi and printed at 300 dpi comes out the same size, while printing it larger reduces its effective resolution. Print speed, a separate specification, is quoted in pages per minute.
