Which printer is also known as a page printer?
- A.Dot matrix printer
- B.Daisy wheel printer
- C.Laser printer
- D.Inkjet printer
Correct answer
Explanation
The correct answer is C, laser printer. It builds the image of a whole page on a photosensitive drum with a laser beam, then picks up dry toner on that image and fuses it onto the paper with heat and pressure. Since it commits to one complete page at a time, its speed is quoted in pages per minute and the machine is called a page printer.
Option A, the dot matrix, is a character printer: its head prints a few characters at a time and its speed is given in characters per second. Option B, the daisy wheel, is also a character printer; it carries fully formed letters on the petals of a wheel and strikes them through a ribbon. Option D, the inkjet, sprays droplets line by line as the head sweeps across the paper, so it is treated as a line-by-line printer rather than a page printer. Character, line and page is the ladder to remember.

- A.Bit
- B.Pixel
- C.Byte
- D.Dot pitch
Show answer
The word is a contraction of picture element. A screen image is a grid of these points, and the number of them across and down the screen is what is quoted as the resolution of the monitor, so a higher pixel count means a finer picture.
