Descritive Answer : IT TOOLS & BUSINESS SYSTEMS Jan-2018 | NIELIT O Level

 Q. 5 (A) : Write the comparison Between Dot Matrix Printers & Laser Printers with respect to Print Quality, Speed, Noise and cost parameters.

Answer

Print Quality

A typical laser printer has a resolution of 1,200 dots per inch, or dpi. It achieves this level of detail through the use of microscopic toner powder, high-performance electronics and precision optics. Many laser printers have color capability at the same high resolution. Some dot matrix printers achieve 240 dpi by making repeated passes over the same printed area, though documents produced this way take at least twice as long to print as those printed at normal quality. As a dot matrix printer's output color depends on the ribbon, virtually none offer choices beyond black and red.

Speed

A typical desktop laser printer turns out about four full-color pages per minute; for black-and-white text, this rises to 25 pages per minute. Dot matrix printers are typically rated at between 200 and 600 characters per second, or about 50 pages per minute in draft mode. Some high-output dot matrix printers achieve 1,100 characters per second, or 100 pages per minute, although the print quality is low-resolution text.
