【正文】 viewing area. Common sizes are 15, 17, 19 and 21 inches. The clarity is indicated by its resolution, which is measured by pixels. The greater the resolution is, the better the clarity of the image is. Printer: A printer shown in figure 115 is one of puter output devices, which is used to print the results of puter processing on paper. There are three indicators to measure the performance of printer. They are print resolution, print speed and noise. The printer has many different types. According to the principle, it can be divided into the subhitting style and the nonimpact style. According to the application, it can be divided into dot matrix printer, color inkjet printer and laser printer.

It can be connected to a puter through the interface, and it bees an important part of office hardware. The important directions of its development are to realize the multifunction, colorization, smallscale and highspeed. Fax: As shown in figure 117 below, a fax is the munication equipment, which converts documents, charts, photographs and other still images into electrical signals with the scan and optical conversion technology and transmits the signals to the receiver in order to copy in the form of record. According to the application, faxes can be divided into photo fax, paper fax, weather fax and file fax.
