Detailed explanation-1: -Whilst all printers will make a noise to some extent, the crown for the noisiest type of printer must go to the dot matrix printer.
Detailed explanation-2: -Dot matrix printers create noise when the pins or typeface strike the ribbon to the paper, and sound-damping enclosures may have to be used in quiet environments. They can only print lower-resolution graphics, with limited color performance, limited quality, and lower speeds compared to non-impact printers.
Detailed explanation-3: -Line Printers A fast line printer can print as many as 3, 000 lines per minute. The disadvantages of line printers are that they cannot print graphics, the print quality is low, and they are very noisy. They are used with mainframe computers where high speed is vital for the large volume of printed output required.
Detailed explanation-4: -Even the best dot matrix printers typically fall short of the quality of ink-jet or laser printers when it comes to print quality because of the number and size of pins in the print head.
